Question

Prove that cos a-sin a +1/cos a +sin a - 1=cosec a +cot a, using cosec2a=1+cot2 a

Answer 1

hey mate , I will give u hint and j hole u will he able to solve it by self
divide the numerator and denominator by sin a
put the value of 1 in the numerator then take (cot a+cosec a) as common and then cancel the denominator. and u will get the RHS
hope it helps
