" ,16."(tan A+sin A)/(tan A-sin A)=(sec A+1)/(sec A-1)

Prove that (i) (tan A+ sin A)/(tan A- sin A)= (sec A+1)/(sec A-1) (ii) (cot A- cos A)/(cot A+ cos A)= ("cosec" A-1)/("cosec" A+1)

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

sqrt((1+sin A)/(1-sin A))=sec A+tan A

tan 2A- sec A sin A =

Prove that : (tan A + sec A - 1)/ (tan A - sec A + 1) = (1 + sin A)/ (cos A)

Prove that: (xiv) (tan A + sec A -1)/(tan A - sec A+1 ) = (1 + sin A)/( cos A)

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

sqrt((1-sin A)/(1+sin A))=sec A-tan A

(tan theta+sin theta)/(tan theta-sin theta)=(sec theta+1)/(sec theta-1)

Prove that (tan theta + sin theta)/(tan theta - sin theta) =(sec theta +1)/(sec theta-1)
