Help With Math

For this activity, the teacher will cut out the square from the table and give each student (or group) the cut out pieces and a blank "board". Students must find trig ratios given 4 right triangles and match the correct trig function of a selected angle to the correct side ratio.

This review worksheet contains problems making students: 1) Find an exact value given a trig function and angle - EX: sin(15) 2) Write an expression as sine, cosine or tangent and find exact value - EX: cos(-2pi)cos(pi)-sin(-2pi)sin(pi) 3) Prove the identity - EX: cos(pi + x) = -cosx
