" 2."(sec A+ran 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 (sec A-tan A)^(2)(1+sin A)=1-sin A

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

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

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

Prove the following identities : cot^(2) A ((sec A - 1)/(1 + sin A)) + sec ^(2) A ((sin A -1)/ (1 + sec A)) = 0

(1-sin A) / (1-sec A) - (1 + sin A) / (1 + sec A) = 2cot A (cos A-cos ecA)

If 0^(@) le A le 90^(@), find A, if : (sin A)/ (sec A - 1) + (sin A)/ (sec A + 1) = 2

tan (45 ^ (@) + (A) / (2)) = sqrt ((1 + sin A) / (1-sin A)) = sec A + tan A

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