[" If "cot theta=(7)/(8)" ,evaluate "],[((1+sin theta)(1-sin theta))/((1+cos theta)(1-cos theta))=((1-sin^(2)theta))/((1-cos^(2)theta))]

If cot theta=(7)/(8), evaluate.1.)((1+sin theta)(1-sin theta))/((1-cos theta)(1+cos theta))

If cot theta = 7/8 , evaluate: (i) ((1+sin theta)(1-sin theta))/((1+cos theta) (1-cos theta))

If cot theta=(15)/(8), then Evaluate ((2+2sin theta)(1-sin theta))/((1+cos theta)(2-2cos theta))

If quad cot theta=(7)/(8) ,evaluate: ( i ) ((1+sin theta)(1-sin theta))/((1+cos theta)(1-cos theta)) (ii)

If cot theta=(7)/(8) then find the value ((1-sin theta)(1+sin theta))/((1-cos theta)(1+cos theta))

(sin theta)/(1-cos theta)=(1+cos theta)/(sin theta)

cos theta/(1+sin theta)=(1-sin theta)/cos theta

Given cot theta =(7)/(8) , then evaluate (i) ((1+sin theta )( 1-sin theta ))/( (1+cos theta )(1-cos theta )) " "(ii) ((1+sin theta ))/( cos theta )
