Answer:
PLEASE REFER TO THE IMAGE ATTACHED...!!!....
STEP BY STEP EXPLANATION :
- TAKE LCM
- SOLVE IT FURTHER
- NOW USE THE TRIGONOMETRIC IDENTITY (sin^2 theta + cos^2 theta =1) AND SUBSTITUTE (sin^2 theta + cos^2 theta) BY 1
- NOW TAKE 2 COMMON
- CUT OUT (1+sin theta) FROM NUMERATOR AND DENOMINATOR
- NOW USE TRIGONOMETRIC IDENTITY (1/cos theta = sec theta) AND SUBSTITUTE (1/cos theta ) BY (sec theta )
- NOW U GET (2sec theta ) WHICH IS EQUAL TO RHS .
- HENCE PROVED.
