`(sin A)/(1+cos A)=(1-cos A)/(sin A)`

Prove that : (sin i)/(1+cos i)=(1-cos i)/(sin i)

(1+cos A)/(sin A)+(sin A)/(1+cos A)=(2)/(sin A)

Show that (1+sin A)/(cos A)+(cos B)/(1-sin B)=(2sin A-2sin B)/(sin(A-B)+cos A-cos B)

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

(sin A)/(1+cos A)+(sin A)/(1-cos A) is (0^@ (0^@ < A<90^@) की स्थिति में (sin A)/(1+cos A)+(sin A)/(1-cos A) कितना होगा?

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

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

Prove the following identities: (cos A)/(1-sin A)+(sin A)/(1-cos A)+1=(sin A cos A)/((1-sin A)(1-cos A))((1+cot A+tan A)(sin A-cos A)/(sec^(3)A-cos ec^(3)A)=sin^(2)A cos^(2)A

Prove that (1 + sin A) / (cos A) + (cos B) / (1-sin B) = (2sin A-2sin B) / (sin (AB) + cos A-cos B)

(cos A)/(1+sin A)+(1+sin A)/(cos A)
