Question

Pls solve this question

Answer 1

Answer:

To prove:

Cos∅/1+Sin∅=1-Sin∅/Cos∅

As we know from trigonometric identities ,

Sin²∅+Cos²∅=1

Cos²∅=1-Sin²∅

(Cos∅)²=1²-(Sin∅)²

We know that,a²-b²=(a+b)(a-b)

Cos∅*Cos∅=(1-Sin∅)*(1-Sin∅)

By rearranging,We get,

Cos∅/1+Sin∅=1-Sin∅/Cos∅

Step-by-step explanation:

Hence,Proved..
