Question: Verify the identity. cot2(t) cos2(t) = cot2(t) cos2(t) cot2(t) - cos2(t) = = - cos(t) COS sin2(t) 1 - 1 = cos2(t) = cos2(t)

Verify the identity. cot2(t) cos2(t) = cot2(t) cos2(t) cot2(t) - cos2(t) =

Verify the identity. cot2(t) cos2(t) = cot2(t) cos2(t) cot2(t) - cos2(t) = = - cos(t) COS sin2(t) 1 - 1 = cos2(t) = cos2(t) Cos (t) ( = - 1)
