Question

plz solve this sum plz plz plz​

Answer 1

Answer:

$\frac{1}{1 + \sin( \alpha ) } + \frac{1}{1 - \sin( \alpha ) } = 2 \sec( {}^{2} \alpha )$

Take LHS:-

$\frac{1}{1 + \sin( \alpha ) } + \frac{1}{1 - \sin( \alpha ) } \\\\ take \: lcm \: \\ \\ \frac{1 + \sin( \alpha ) + 1 - \sin( \alpha ) }{1 - \sin( {}^{2} \alpha ) } \\ \frac{2}{ \cos( {}^{2} \alpha ) } = 2 \: \sec( {}^{2} \alpha ) \: \: = RHS$

Proved.
