First some review…To integrate, you must have a sum/difference
or constant multiple combination of a variable to a number power (xn).
You may need to substitute one function for another in order to manipulate the integral to be in this form!
Integration finds net area between curves by accumulating heights.

Now you’re ready to play!Designate one person in your group to “keep
score”. This person should draw a blank Tic-Tac-Toe board on a piece of paper. Keep track of which spaces you have filled in on this board by marking an X for the ones you get correct and an O for the ones do you not.
Remember: Your goal is to make three X’s across, down, or diagonally (just like in normal Tic-Tac-Toe). First group to accomplish this, wins 10 bonus points!

Application Answer Recall…the area above the x-axis is positiveand the area below the x-axis is negative in integration.
Using geometric shapes, divide thepositive region into a triangle from [-1,0], arectangle from [0,1], and a triangle from [1,2]. Add these up! 1+2+1 = 4
Subtract the triangular region from [2,3] and the rectangular region from [3,4]. 4-.5-1 = 2.5

Application Answer
Since we need 3 equal subdivisions, use:A1= the area from [1,3], ∆x = 2A2= the area from [3,5], ∆x = 2 and A3= the area from [5,7], ∆x = 2.
A1= (2)(f(2)) = 2(2) = 4A2= (2)( f(4))= 2(2) = 4A3= (2)( f(6)) = 2(-1) = -2
A1+ A2+ A3 = 4+4+-2 = 6.

ApplicationThe temperature T (in ˚C) recorded during a day
followed the curve where t is time and noon is t = 0. (In other words, for this day, -12 ≤ t ≤ 12.)
What was the average temperature during the day?

Application Answer
For average temperature, “add up all the temperatures and divide by the number of temperatures accumulated.”
