It is very simple ...Just multiply each terms in LHS you will get the result ..
(secA - cosecA)(1+tanA+cotA)
= secA + tanA.secA + cotA.secA - cosecA - cosecA.tanA - cosecA.cotA
= secA + sinA.sec^2A + cosecA - cosecA - secA - cosec^2A.cosA
= sinA/cos^2A - cosA/sin^2A
= (sinA/cosA)secA - (cosA/sinA)cosecA
= tanA.secA - cotA.cosecA ( RHS )
(secA - cosecA)(1+tanA+cotA)
= secA + tanA.secA + cotA.secA - cosecA - cosecA.tanA - cosecA.cotA
= secA + sinA.sec^2A + cosecA - cosecA - secA - cosec^2A.cosA
= sinA/cos^2A - cosA/sin^2A
= (sinA/cosA)secA - (cosA/sinA)cosecA
= tanA.secA - cotA.cosecA ( RHS )
ok
