Step-by-step explanation:

LHS

= (sinA)^2/cosA(sinA - CosA) - (cosA)^2/SinA(SinA - CosA)

= tanASinA/(sinA - CosA) - cotAcosA/(sinA - CosA)

= (tanASinA - cotAcosA)/(sinA - CosA)

= [(sinA)^2/cosA - (cosA)^2/sinA]/(sinA - CosA)

= [(sinA)^2/cosA - (cosA)^2/sinA]/(sinA - CosA)

= [(sinA)^3 - (cosA)^3]/(sinA - CosA)*CosASinA

= (sinA - cosA)[(sinA)^2 + (cosA)^2 + sinAcosA]/(sinA - CosA)sinAcosA

= 1 + tanA + cotA
