1). Use the half-angle formulas to determine the exact values of the sine, cosine, and tangent of the angle.π/127 sin(π/12) =9 cos(π/12) =3 tan(π/12) =2).Consider the following formulas.a sin(Bθ) + b cos(Bθ) = √a2 + b2 sin(Bθ + C), where C = arctan(b/a) and a > 0a sin(Bθ) + b cos(Bθ) = √a2 + b2(Bθ – C), where C = arctan(a/b)and b > 0Use the formulas given above to write the trigonometric expression in the following forms.12 sin(3θ) + 16 cos(3θ)(a) √a2 + b2 sin(Bθ + C)(b) √a2 + b2 cos(Bθ – C)
