Question

prove that cot A+cosec A-1 / cot A - cosec A +1 = 1+cos A / 1+ sin A​

Answer 1

Answer:

hey this is correct answer.

(i) L.H.S. = (cot A + cosec A – 1)/(cot A – cosec A + 1)

= (cot A + cosec A) – (cosec2 A – cot2 A)/cot A - cosec A + 1

= cot A + cosec A = cos A/sin A + 1/sin A

= cos A + 1/sin A = R.H.S.

Hence proved..
