Bros plzzz solve this fast and anyone who spams will be reported immediately

Answer 1

Step-by-step explanation:

1) To prove : “(1-cos² θ ) sec² θ = tan² θ ”

2) Inference ( Understanding the question, Thinking of the method ) : We shall start from Left hand side ( L. H. S) and proceed till we get R. H. S. We will use trigonometric identities too.

3) Formulas we are going to use :

\rightarrow→ 1 -cos²θ = sin²θ

\rightarrow→ tanθ = sinθ * secθ

4) Actual proof :

Firstly, We know that, sin²θ + cos²θ = 1 , So, 1 - cos²θ = sin²θ
