Question

find seca + tan a (1 - sina )​

Answer 1

Step-by-step explanation:

$\sec(a) + \tan(a) - \tan(a) \sin(a) \\ \frac{1}{ \cos(a) } + \frac{ \sin(a) }{ \cos(a) } - \frac{ { \sin(a) }^{2} }{ \cos(a) } \\ \frac{1 - { \sin(a) }^{2} + \sin(a) }{ \cos(a) } \\ \frac{ { \cos(a) }^{2} + \sin(a) }{ \cos(a) }$
