Question

please solve this it's very urgent​

Answer 1

Answer:

= √(1+sin x)/√(1-sin x) × √(1+sin x) /√(1+sin x)

= (1+ sin x )/√(1-sin²x) = (1+ sin x )/cos x

= ( 1/cos x +sin x/cos x ) = ( sec x + tan x ).

ANSWER!

So option b) is correct

Answer 2

√1-sinx/1+sinx=√1-sinx/1+sinx*1-sinx/1-sinx

√(1-sinx) '2/1-sin'2x=1-sinx/cosx= secx-tanx

answer is secx-tanx
