Question

(sinΦ+cosΦ)(tanΦ+cotΦ)=secΦ+cosecΦ

Answer 1

Answer:

$( \sin(x) + \cos(x) )( \frac{ \sin(x) }{ \cos(x) } + \frac{ \cos(x) }{ \sin(x) } )$

$( \sin(x) + \cos(x) )( \frac{ { \sin }^{2}x + { \cos }^{2} x }{ \sin(x) \cos(x) } )$

$\frac{\sin(x) + \cos(x)}{ \sin(x) \cos(x) }$

$\sec(x) + \csc(x)$
