Question

sin theta + 1 - cos theta by cos theta - 1 + sin theta is equal to 1 + sin theta by cos theta

Answer 1

Answer:

Step-by-step explanation:

RHS:

     dividing num and den by cos∅

=(tan∅+sec∅-1)/(1-sec∅+tan∅)

=[tan∅+sec∅-(sec²∅-tan²∅)]/(1-sec∅+tan∅)           (∵sec²∅-tan²∅=1)

=(sec∅+tan∅)(1-sec∅+tan∅)/1-sec∅+tan∅)

=(sec∅+tan∅)

=(1+sin∅)/cos∅

∴Hence Proved
