(a) Find the exact value of each x ∈ [0, 2π) for which sin(2x) = √ (3 cos(x)). (b) Determine the value of cos^(−1) sin ( −7π/ 3 ))...If you use a definition, explicitly cite it by using the phrase “by the definition of . . . .” • If you use a theorem (or a rule, a test), explicitly cite it by using the phrases “by theorem . . . .”
