" hat- "quad (sin A)/(1+cos A)+(1+cos A)/(sin A)=2cosec A

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

Prove that : (sin A)/ (1 + cos A) + (1 + cos A)/ (sin A) = 2 cosec A

Prove that (sin A)/(1 + cos A) + (sin A)/(1 - cos A) = 2 cosec A.

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

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

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

The value of ((sin A)/(1-cos A)+(1-cos A)/(sinA) div ((cot^2 A)/(1+cosec A)+1) is:

Prove that: (sin A + cos A)/(sin A - cos A) + (sin A - cos A)/(sin A + cos A) = (2)/(sin^(2)A-cos^(2)A)=(2)/(2sin^(2)A-1)=(2)/(1-2 cos^(2)A) .

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)

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