Answer 2

Heya!!!

Answer to your question:

To make it a bit convenient for me, let's take theta=x.
${ \sec(x) }^{2} (1 + \sin(x) )(1 - \sin(x) ) = k$
${ \sec(x) }^{2} (1 - { \sin(x) }^{2} ) = k$
${ \sec(x) }^{2} { \cos(x) }^{2} = k$
$\frac{1}{ { \cos(x) }^{2} } { \cos(x) }^{2} = k$
$k = 1$

Hope it helps ^_^
