Answer 2

$\huge\bf\underline{\underline{\pink{A}\orange{N}\blue{S}\red{W}\green{E}\purple{R}}}$

$\large \red {\bf \: GIVEN : \frac{ \bf cos A }{ \bf1 + \bf \: sin A} \: + \frac{ \bf 1 + sin A }{ \bf \: cos A} = \bf2 \: sec \: A}$

$\large \purple {\bf \: TO \: PROVE : LHS = RHS }$

$\huge\sf{\underline{\pink{SOLUTION!}}}$

$\large = \bf \: LHS$

$\large \bf = \frac{ \bf cos A }{ \bf1 + \bf \: sin A} \: + \frac{ \bf 1 + sin A }{ \bf \: cos A}$

$\large \bf = \frac{ {cos}^{2}A + (1 + sinA {}^{2} )}{cosA(1 + sinA)}$

$\large \bf = \frac{cos^{2}A + 1 + sin ^{2} A + 2sin A}{cosA(1 + sinA)}$

$\large \bf = \frac{2 + 2sinA}{cosA(1 + sinA)}$

$\large \bf = \frac{2}{cosA}$

$\large \bf = 2secA$

$\large \bf = RHS$
