${\tt{\red{\underline{\large{Given}}}}}$

• A trignometic identity

${\sf{\green{\underline{\large{To\:find}}}}}$

• LHS = RHS

${\sf{\pink{\underline{\Large{Explanation}}}}}$

Cot∅+tan∅=sec∅×cosec∅

__________________________

Let break cot and tan

LHS

cos/sin +Sin/cos

=>( sin²+cos²)/sin×cos

we know that sin²+cos²=1

=>1/cos∅.sin∅

=>1/cos∅ × 1/ sin∅

=>cosec∅×sec∅

______________________________

Hence verified LHS =RHS
