Question

1+cot2theatha/cosectheatha=cosecthetha

Answer 1

Let A be theta

Step-by-step explanation:

To prove : 1 +cos^2 A / cosecA= cosecA

LHS:1+cos^2 A/cosecA

We know that 1 + cos^2A =cosec^2 A

So, 1 + cos^2 A / cosec A

cosec^2 A / cosec A

cosec A × cosec A / cosec A

=cosec A = RHS

Therefore LHS = RHS

Hence proved
