Given LHS = (1 + cotA + tanA)(sinA - cosA)
= (1 + cosA/sinA + sinA/cosA)(sinA - cosA)
= (sinAcosA + sin^2A + cos^2A/sinAcosA)(sinA - cosA)
= [(1 + sinAcosA/sinAcosA)](sinA - cosA).
Given RHS = sinAtanA - cotAcosA
= sinA * sinA/cosA - cosA/sinA * cosA
= sin^2A/cosA - cos^2A/sinA
= sin^3A - cos^3A/sinA - cosA
We know that a^3 - b^3 = (a - b)(a^2 + ab + b^2)
= (sinA - cosA)(sin^2A + cos^2A + sinAcosA)/sinAcosA
= (sinA - cosA)[(1 + sinAcosA)/sinAcosA]
LHS = RHS.
Hope this helps!
