(tan A)/(1+sec A)-(tan A)/(1-sec A)=2cosec A

Prove that (tan A)/(sec A-1)+(tan A)/(sec A+1)=2 cosec A .

Prove that (tan A)/(sec A -1) + (tan A)/(sec A +1) = 2 cosec A

(1+tan A)/(sin A)+(1+cot A)/(cos A)=2(sec A+cosec A)

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

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

(tan A+cot A)=(sec A*csc A)

" (i) "(1+sec A+tan A)(1-cosec A+cot A)=2

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

(sec A (sec A + tan A)(1-sin A))/ ((cosec^2 A-1)sin^2 A) is equal to: (sec A (sec A + tan A)(1-sin A))/ ((cosec^2 A-1)sin^2 A) का मान क्या होगा ?
