In Exercises 63–65, determine whetherthe statement is true or false. Justify your answer.63. tan x2 = tan2 x 64. cos(θ − π2) = sin θ65. The equation sin2 θ + cos2 θ = 1 + tan2 θ is an identitybecause sin2(0) + cos2(0) = 1 and 1 + tan2(0) = 1. True or False? In Exercises 63–65, determine whetherthe statement is true or false. Justify your answer.64. cos( 0 –- =)63. tan x² = tan² xsin 065. The equation sin² 0 + cos² 0 = 1 + tan² 0 is an identitybecause sin (0) + cos²(0) = 1 and 1 + tan²(0) = 1.
