Q: Verify the identity. 4 cos(sin-1 x) = V 16 – 16x? Let e = sin-1 x = sin e = x = X. * Thus, 4…

A: Explanation of the answer is as follows

Q: Verify the identity. (sin(t) + cos(t))² sin(t) cos(t) sec(t) csc(t) = 2 +

A: sin(t)+cos(t)2sin(t) cos(t)=2+sec(t)csc(t)

Q: Verify the identity.

A: (sec2θ-1)cotθtanθsinθ+cosθ=sinθ

Q: Verify.

A: We will use tanx= sinx/cosx and secx= 1/cosx We plug them in the left side of the expression.

Q: Verify the identity.
