L.H.S = (1 + cotA)/secA = (1 + cosA/sinA)/(1/cosA) = {cosA(sinA +� cosA)}/sinA = cotA(sinA + cosA) = cosA + cos2A/sinA R.H.S = sinA.SinA/(1 -cosA) = {sin2A(1 + cosA)}/{(1 – cosA)(1 + cosA)} = �{sin2A(1 + cosA)}/(1 – cos2A) = {sin2A(1 + cosA)}/sin2A = 1 + cosA L.H.S doesn’t matches with R.H.S (please check your question)
