8.3-8.5 Review Problems (Problems from notes or quizzes)
Here is a great way to study for a math test. Directions: Work out problems on separate pieces of
notebook paper & then check solution with the one already listed on lesson handout or in notebook that
we did together in class during the unit.
1) Examples from 8.4 Sum & Difference Formulas Handout
(Find exact value, find condensed form (single angle), verify or establish the identity)
2) Examples from 8.5 Double & Half Angle Formulas Handout (Find exact value, use triangles & quadrant
plane to figure out exact values of expressions expanded out)
3) 2 Verify the Identities problems on back of Goldenrod Quiz (front side was 17 trig identities). Show
all work (write statements & reason for each verifying identity problem).
