Prove: (sec A-tan A)^(2)=(1-sin A)/(1+sin A)

Prove that (sec A-tan A)^(2)(1+sin A)=1-sin A

(sec A+ tan A) (1 - sin A) equals to

( sec A + tan A ) ( 1 - sin A ) = ?

Prove that : tan (pi/4 - A/2) = sec A - tan A = sqrt((1-sin A)/(1+ sin A))

(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 ?

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

tan((pi)/(4)-(A)/(2))=sec A-tan A=sqrt((1-sin A)/(1+sin A)A)

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

Prove: (sec A-tan A)/(sec A+tan A)=(cos^(2)A)/((1+sin A)^(2))
