Answer 2

Answer:

Answer ⤵️

sec² A = tan² A + 1 and

cosec² A = cot² A + 1

On Adding these , we get :

sec² A + cosec² A = tan² A + cot² A + 2

sec² A + cosec² A = tan² A + cot² A + 2 tan A cot A = ( tab A + cot A ) ²

√ sec² A + coses² A = tan A + cot A

is your right answer

I hope answer is helpful to us
