Double and Half Angle Identities - Practice 4 Forms (A,B,C and D)

These are 4 forms practice on double and half angle identities. Each form contains 5 challenging problems. The first problem is finding the exact value of trigonometric function using half angle identities. The second problem is evaluating a trig function of double angle 2α given the value of trig function of angle α and in which quadrant lies the angle alpha. The third problem is finding the values of three trig functions of angle alpha, half alpha or double alpha given the value of one trig function and in which quadrant lies the angle alpha. The fourth problem is simplifying two expressions and the fifth problem is proving an identity.

The product can be used as independent practice, extra practice, group activity (groups of 2,3 and/or 4), enrichment, homework, and as an assessment.

Answer keys are included.
