सिद्ध कीजिए की `(sin A-sin B)/(cos A + cosB) = tan""(A-B)/2`

Prove that (sin A-sin B)/(cos A+ cos B) = "tan" (A-B)/2

(sin A + sin B) / (cos A + cos B) = tan ((A + B) / (2))

Prove that: (sin A-sin B)/(cos A+cos B)=tan((A-B)/2)

Prove that (sin A+sin B)/(cos A+cos B)=tan((A+B)/2)

Prove that: (sin A+sin B)/(cos A+cos B)=tan((A+B)/2)

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

(sin^2A-sin^2B)/(sinA.cosA-sinB.cosB)=....

Prove the following identities : tan^(2) A - tan^(2) B = (sin^(2) A - sin^(2) B)/ (cos^(2) A . cos^(2) B)

If sin A=sin B and cos A = cosB, find A in terms of B

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