LHS = 1cosec A − cot A − 1sin A=1cosec A − cot A×cosec A + cot Acosec A + cot A − 1sin A=cosec A + cot Acosec2A − cot2A − 1sin A=cosec A + cot A1 − 1sin A=cosec A + cot A − cosec A= cot A
RHS = 1sin A − 1cosec A + cot A=1sin A − 1cosec A + cot A ×cosec A − cot Acosec A − cot A=1sin A − cosec A − cot Acosec2A − cot2A=1sin A − cosec A − cot A1=1sin A − (cosec A − cot A)=cosec A − cosec A + cot A=cot ASo, LHS = RHS(Proved)
