Dear student
1/CosA - 1/SinA (1+sinA/CosA + CosA/SinA)
= (SinA-cosA)/SinAcosA)((SinACosA + Sin^2A + Cos^2A)/(SinACosA)
=(Sin^3A - Cos^3A) /SinA CosA
= TanA SecA - CotACosecA
1/CosA - 1/SinA (1+sinA/CosA + CosA/SinA)
= (SinA-cosA)/SinAcosA)((SinACosA + Sin^2A + Cos^2A)/(SinACosA)
=(Sin^3A - Cos^3A) /SinA CosA
= TanA SecA - CotACosecA

Dear student
LHS
(1/ cosA - 1/sinA ) (1 + sinA/cosA + cosA /sinA)
= ((SinA-cosA)/sinA cosA)((sinA cosA + sin²A + cos²A)/sinA cos A)
= (Sin³A - cos³A)/ sinA cosA
= TanA secA - cotA cosecA
RHS
Hence proved.
