Question

cosA/1-sinA +sinA/1-cosA +1/1=sinA*cosA/1-sinA*1-cosA​.please guys help me find it​

Answer 1

Step-by-step explanation:

taking lhs

cosA/1-sinA + sinA/1-cosA + 1/1

(cosA - cos^2A + sinA - sin^2 + 1-sinA - cosA+sinAcosA)/(1-sinA)(1-cosA)

-1(cos^2A + sin^2A) + 1 +sinAcosA/(1-sinA)(1-cosA)

-1+1 +sinAcosA/(1-sinA)(1-cosA)

sinAcosA/1-sinA(1-cosA)proved
