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

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

tan 2A- sec A sin A =

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

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

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

(sec A-cos A)(cot A+tan A)=tan A.sec A

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

(cos ecA-sin A) (sec A-cos A) sec ^ (2) A = tan A
