Question

cosecA- cotA= underroot 1- cosA/ underroot 1+ cosA

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Taking RHS

√1-cosa/1+cosa

Multiply by 1-cosa/1-cosa

√1-cosa/1+cosa ×1-cosa/1-cosa

In denominator using identity (a+b)(a-b) and in numerator (1-cosa)^2

So √1-cosa)^2/1-cos^2a

1-cos^2a=sin^2a

So √(1-cosa)^2/sin^2a

1-cosa/Sina =1/sina-cosa/Sina
