Comments on the Paper Commentaires sur les epreuves

Overall CommentsCongratulations to all of the participants in the 2019 Euclid Contest. The average score in 2019 was 54.8. Wewere very pleased that almost all students achieved some success on the early parts of the paper. At the sametime, the later parts of these problems managed to challenge the top students even more than last year’s problems.Special congratulations go to the 131 official contestants who achieved scores of 90 and higher this year.

We at the Centre for Education in Mathematics and Computing believe strongly that it is very important forstudents to both learn to solve mathematics problems and learn to write good solutions to these problems. Manystudents do a reasonable job of writing solutions, while others still include no explanation whatsoever.

Special thanks go to the Euclid Committee that annually sets the Contest problems and manages to achievea very difficult balancing act of providing both accessible and challenging problems on the same paper.

To the students who wrote, the parents who supported them, and the teachers who helped them along theway, thank you for your continuing participation and support. We hope that you enjoyed the Contest and relishedthe challenges that it provided. We hope that mathematics contests continue to feed your love for and interest inmathematics.

Specific Comments

1. Average: 9.4Very well done. A common error in part (b) was ignoring the requirement that a be an integer.

2. Average: 9.2In part (a), many students used an incorrect formula for area, or used incorrect radii for the circles. A commonerror in part (b) was to correctly determine the elapsed time and then apply it to the incorrect starting time.For part (c), common errors included substituting the coordinates of the point (9, 2) incorrectly.

3. Average: 8.9Part (a) was well done. A common error in part (b) was to say that 324/3 was equal to 168/3. In part (c),which required application of exponent laws, the most common errors came from applying logarithmic lawsincorrectly.

4. Average: 7.5Part (a) was reasonably well done. A common source of difficulty was not realizing that4ADC is an isoscelestriangle. A common misconception in part (b) was that the x- and y-coordinates needed to be equal, andthis led to finding only one of the possible solutions.

5. Average: 4.8Part (a) was done fairly well, but there was often not much work shown. Some students who solved this bytrial and error were only able to find one answer. Common mistakes included looking at numbers that addto 50, or giving the answer of (a, b) =

(√2,√

32),(√

8,√

18).

For part (b), a high percentage of students made the connection to positive divisors of 2000. Students whodid not make this connection often worked with the first equation and began counting pairs that add to2000. Common mistakes included not being explicit about why the positive divisors of 2000 were listed, ormiscounting the number of divisors.

6. Average: 3.6In part (a), most students were able to calculate the interior angle in the pentagon, but many students werestopped at this point. Many students incorrectly assumed the diagram was to scale, and would use it toconstruct a polygon with either 10 or 11 sides.

Comments on the Paper Commentaires sur les epreuves

There were many ways to solve part (b), including coordinatizing, using similar triangles, slopes of lines,tangents, vectors, Pythagorean Theorem, and using other less-known geometric formulas and properties.Most attempts that we saw had an argument that used similar triangles somehow. Common mistakesincluded assuming the conclusion, using weak or not properly justified arguments, and large jumps in logic.Some students scaled the problem by fixing a value for AD, which is acceptable since this makes AD theunit of measure. However, some students also fixed a value for the common ratio in the geometric sequence,which results in a “proof” by example.

7. Average: 5.0Most students either knew how to do part (a) or did not. Common mistakes included using incorrectlogarithm rules or using correct rules incorrectly, and not excluding the values of x that violate the domainof the logarithm.Part (b) was done fairly well. Most students solved the problem as we did in our solutions; however, manystudents expanded f(f(f(x))) into a degree 8 polynomial and then looked for the roots. For full marks,students needed to show the algebraic steps to find these roots, rather than simply writing these numbersdown. Common mistakes included not working through enough layers of the composition and also discountingthe irrational roots.

8. Average: 2.5It was great to see so many correct final answers for part (a). Most students correctly identified right anglesat the centre of the circle and points of tangency. The Pythagorean Theorem, similar triangles and/ortrigonometry were then commonly used to find the length of DS. Marks were sometimes deducted for notjustifying this sufficiently, using inexact values to end with an approximate value close to 0.35, or supplyingan unsimplified final answer such as tan (sin−1 (1

3)).Part (b) seemed to stump many students. The biggest hurdle was to realize that cos θ + sin β = π

2 in the

first quadrant and apply this to θ = 32 cosx and β = 3

2 sin x. It was important to explain why 0 < θ <π

2and 0 < β <

π

2 . Students who made this observation were often able to square both sides and yield thecorrect final answer.

9. Average: 3.5The first two parts of Question 9 were done very well but the contest became particularly difficult in thesecond half of this question. In part (c), we did see some very nice solutions. One approach used a quadraticsolution as in the posted solution but it was more common to see the problem broken into cases using thefact that every integer can be written in the form 3k, 3k + 1 or 3k + 2, where k is an integer. A smallnumber of students noticed a pattern involving Fibonacci numbers in part (d) but even fewer fully justifiedthe correctness of their answers.

10. Average: 0.4Question 10 was very challenging and involved understanding there different scenarios involving probability.Since there were many attempts to answer part (a), we recommend reading the solutions to see one way toget the correct answer of 7

Comments on the Paper Commentaires sur les epreuves

Commentaires GenerauxFelicitations a tous les participants du Concours Euclide 2019. La note moyenne etait 54,8. Nous avons eu leplaisir de constater que presque tous les eleves ont eu du succes dans les premieres questions. De plus, les dernieresparties de ces problemes presentaient un plus grand defi pour les meilleurs etudiants que l’annee derniere. Desfelicitations speciales vont aux 131 concurrents officiaux qui ont atteint une note superieure ou egale a 90 sur 100.

Le Centre d’education en mathematiques et en informatique croit fortement qu’il est tres important pour lesetudiant(e)s d’apprendre a resoudre des problemes de mathematiques ainsi que d’apprendre a ecrire de bonnessolutions a ces problemes. Plusieurs etudiants developpent leurs solutions resonablement bien, tandis que d’autresn’inclus aucune explication avec leurs reponses.

Un grand merci va au comite du concours Euclide qui rassemble annuellement les problemes du concours etreussit a accomplir la tache difficile de concevoir des problemes accessibles et stimulants sur le meme examen.

Un grand merci aux etudiant(e)s qui ont ecrit, aux parents qui les ont soutenus et aux enseignant(e)s qui lesont aides pour votre participation continue et votre soutien. Nous esperons que vous avez apprecie le concours etsavoure les defis qu’il a presentes. Nous esperons que les concours de mathematiques continuent a nourrir votreamour et interet pour les mathematiques.

Remarques particulieres

1. Moyenne: 9,4Ce probleme a ete tres bien reussi. Une erreur courante dans la partie (b) consistait a ignorer la conditionque a devait etre un entier.

2. Moyenne: 9,2Dans la partie (a), de nombreux etudiants ont utilise une formule incorrecte pour l’aire ou utilise des rayonsincorrects pour les cercles. Une erreur courante dans la partie (b) etait de determiner correctement le tempsecoule puis de l’appliquer a une heure de debut incorrecte. Pour la partie (c), les erreurs courantes setrouvaient dans la substitution incorrecte des coordonnees du point (9, 2).

3. Moyenne: 8,9La partie (a) a ete bien reussie. Une erreur courante dans la partie (b) etait de dire que 324/3 etait egal a168/3. Dans la partie (c), qui necessitait l’application des lois des exposants, les erreurs les plus courantesprovenaient de l’application incorrecte des lois logarithmiques.

4. Moyenne: 7,5La partie (a) a ete raisonnablement bien reussie. Une source de difficulte courante etait de ne pas realiser que4ADC est un triangle isocele. Une idee communement fausse dans la partie (b) etait que les coordonneesx- et y- devaient etre egales, ce qui a conduit a ne trouver qu’une des solutions possibles.

5. Moyenne: 4,8La partie (a) a ete assez bien reussie, mais souvent, peu de travail presente. Certains etudiants, qui ontresolu ce probleme par tatonnement, n’ont pu trouver qu’une seule reponse. Rechercher des nombres quis’ajoutent a 50, ou repondre (a, b) =

(√2,√

32),(√

8,√

18)

etaient les erreurs les plus courantes.Pour la partie (b), un pourcentage eleve d’etudiants a etabli la connexion avec des diviseurs positifs de 2000.Les etudiants qui ne l’ont pas fait ont souvent travaille avec la premiere equation et ont commence a compterles paires qui s’ajoutent a 2000. Les erreurs courantes etaient notamment de ne pas expliquer de facon clairepourquoi les diviseurs positifs de 2000 etaient repertories ou faire des erreurs de decompte du nombre dediviseurs.

6. Moyenne: 3,6Dans la partie (a), la plupart des etudiants etaient capables de calculer l’angle interieur dans le pentagone,

Comments on the Paper Commentaires sur les epreuves

mais de nombreux etudiants se sont arretes la. De nombreux etudiants ont suppose, a tort, que le diagrammeetait a l’echelle et l’ont utilise pour construire un polygone de 10 ou 11 cotes.Il y avait de nombreuses facons de resoudre la partie (b), y compris en attribuant des coordonnees, en util-isant des triangles similaires, des pentes de lignes, des tangentes, des vecteurs, le theoreme de Pythagore,et en utilisant d’autres formules et proprietes geometriques moins connues. La plupart des tentatives quenous avons vues appliquaient un raisonnement utilisant des triangles similaires. Parmis les erreurs courantes,mentionnons, conclusion presupposee, en utilisant des arguments faibles ou mal justifies et de grands rac-courcis dans le raisonnement. Certains etudiants ont adapte le probleme en attachant une valeur a AD,ce qui est acceptable dans la mesure ou cela fait de AD l’unite de mesure. Cependant, certains etudiantsont egalement attache une valeur pour le rapport commun dans la sequence geometrique, ce qui donne une”preuve” par l’exemple.

7. Moyenne: 5,0Pour la plupart des etudiants, soit ils savaient comment resoudre la partie (a) soit ils ne savaient pas.L’utilisation de logarithmes incorrects ou de regles correctes mais mal employees etaient des erreurs courantes,de meme que le fait de ne pas exclure les valeurs de x qui enfreignent le domaine du logarithme.La partie (b) a ete assez bien reussie. La plupart des etudiants ont resolu le probleme comme nous l’avonsfait dans nos solutions. Cependant, de nombreux etudiants ont developpe f(f(f(x))) en un polynome dedegre 8, puis ont recherche les racines. Pour obtenir la totalite des points, les etudiants devaient montrerles etapes algebriques pour trouver ces racines, plutot que de simplement les ecrire. Ne pas suffisammentdetailler son travail et ne pas tenir compte des racines irrationnelles etaient des erreurs courantes.

8. Moyenne: 2,5C’etait formidable de voir autant de reponses correctes pour la partie (a). La plupart des etudiants ontcorrectement identifie les angles droits au centre du cercle ainsi que les points de tangence. Le theoreme dePythagore, les triangles similaires et/ou la trigonometrie ont ensuite ete generalement utilises pour trouverla longueur de DS. Des points ont parfois ete retires dans le cas ou les justifications etaient insuffisantes, oudes valeurs inexactes etaient utilisees pour aboutir a une valeur approximative de 0, 35, ou lorsque la reponsefinale donnee n’etait pas simplifiee, telle que tan (sin−1 (1

3)).Il semble que la partie (b) a deroute de nombreux etudiants. Le plus gros obstacle etait de realiser quecos θ + sin β = π

2 dans le premier quadrant et de l’appliquer a θ = 32 cosx et β = 3

2 sin x. Il etait important

d’expliquer pourquoi 0 < θ <π

2 et 0 < β <π

2 . Les etudiants ayant fait cette observation etaient souventcapables de concilier les deux cotes et de donner la bonne reponse.

9. Moyenne: 3,5Les deux premieres parties de la question 9 ont ete tres bien reussies, mais le concours est devenu partic-ulierement difficile dans la seconde partie de cette question. Nous avons vu de tres bonnes solutions dans lapartie (c). Une approche utilisait une solution quadratique comme dans la solution publiee mais il etait pluscourant de voir le probleme divise en cas, en utilisant le fait que chaque entier pouvait etre ecrit sous la forme3k, 3k + 1 ou 3k + 2, ou k est un entier. Un petit nombre d’etudiants a remarque une tendance impliquantdes nombres de Fibonacci dans la partie (d), mais encore moins ont pleinement justifie l’exactitude de leursreponses.

10. Moyenne: 0,4La question 10 etait tres difficile et necessitait la comprehension de differents scenarios impliquant des prob-abilites. Comme il y a eu de nombreuses tentatives pour repondre a la partie (a), nous vous recommandonsde lire les solutions pour y voir un moyen d’obtenir la bonne reponse : 7
