Question

Prove that (1 + tan² v) (1 - sin v)(1 + sin v) = 1.

Answer 1

Step-by-step explanation:

by using identities. solve the Lhs.

Answer 2

Answer:

Here you go:

Firstly, we write the formula of (1+tan^2x)

sec^2v * ( 1-sin^2v)

sec^2v * cos^2v

Since, sec and cos are reciprocal of each other so,

1 Hence, proved.

Step-by-step explanation:
