:'=(cos A-sin A+1)/(cos theta+sin A-1)=cos e(A+cot A

prove that (cos A-sin A + 1) / (cos A + sin A-1) = cos ecA + cot A

Prove that (cos theta-sin theta+1)/(cos theta+sin theta-1)=csc theta+cot theta

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

Prove that (cos^3 theta-sin^3 theta)/(cos theta-sin theta) = 1+cos theta sin theta

(tan A) / (1-cot A) + (cot A) / (1-tan A) = 1 + tan A + cot A = 1 + sec A cos ecA (1 + cos theta + sin theta) / (1 + cos theta-sin theta) = (1 + sin theta) / (cos theta)

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

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 )

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 )

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