2. Use the unit circle diagram of the standard position angle A to calculate several trigono- metric values: ( please provide the exact values, involving fractions or possibly square roots. In parts (e), (f), and (g), use relevant angle addition/subtraction or double angle / half angle formulas) (a) cos A (b) sin A (c) tan A (d) sin ( - 0) (e) tan(2A) (f) cos( A + 4. ) (g) cos( A/2) cot A CSC A - 1 3. Show why =0 CSC A + 1 Cot A
