Guided Notes – 8/22/17 or 8/23/17
Objectives: I can evaluate secant and cosecant for all radian measures.
I can evaluate all six trig functions given any angle in the coordinate plane.
Concept Development
o Start by defining sine and cosine.
o How could we calculate sec (7 π4 ) given that secant and cosine are reciprocals of each other?
o Using complete sentences, summarize how we can calculate secant and cosecant of any radian measurement.
Concept Application
o Calculate each of the following using the unit circle.
csc( 7 π6 )=¿ ▪ csc( 3 π4 )=¿
sec (−2π3 )=¿¿ ▪ csc(−3 π2 )=¿
sec (π2 )=¿ ▪ sec (11 π6 )
Concept Development
o What if we were given any angle and a terminal point in the coordinate plane, is there a way to calculate all six
trig functions of that angle?
o Find the six trig functions for the following angle measurement of θ.
