\mathfrak{\huge{\red{\underline{\underline{ANSWER :}}}}}

LHS = ( 1 + secA )/secA

= ( 1 + 1/cosA ) / ( 1/cosA )

= [ ( CosA + 1 ) / cosA ] / ( 1/ cosA )

= Cos A + 1

= ( 1 + cosA ) ( 1 - cosA ) / ( 1 - cosA )

= ( 1 - cos² A ) / ( 1 - cosA )

= Sin² A / ( 1 - cosA )

= RHS

Hope it will help you.

Answer:

LHS = \frac{(1 + secA)}{secA}     \\ </p><p>=  \frac{ \frac{1 + 1}{cosA} }{ \frac{1}{cosA} }    \\ </p><p>= \frac{ \frac{(CosA + 1}{cosA} )}{  ( 1 cosA)}    \\ </p><p>= Cos A + 1 \\ </p><p>=  \frac{( 1 + cosA ) ( 1 - cosA )}{ ( 1 - cosA )}  \\ </p><p>=  \frac{( 1 - cos A )}{( 1 - cosA )}    \\ </p><p>=  \frac{ Sin A }{( 1 - cosA )}  \\ </p><p>= RHS</p><p>
