integral of (sin(x)+sec(x))/(tan(x))

\int \frac{sin ( x ) + sec ( x )}{tan ( x )} d x

sin (x) + ln tan (\frac{x}{2}) + C

Solution steps

\int \frac{sin ( x ) + sec ( x )}{tan ( x )} d x

Expand

\frac{sin ( x ) + sec ( x )}{tan ( x )} : \frac{sin ( x )}{tan ( x )} + \frac{sec ( x )}{tan ( x )}

= \int \frac{sin ( x )}{tan ( x )} + \frac{sec ( x )}{tan ( x )} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{sin ( x )}{tan ( x )} d x + \int \frac{sec ( x )}{tan ( x )} d x

\int \frac{sin ( x )}{tan ( x )} d x = sin (x)

\int \frac{sec ( x )}{tan ( x )} d x = ln tan (\frac{x}{2})

= sin (x) + ln tan (\frac{x}{2})

Add a constant to the solution

= sin (x) + ln tan (\frac{x}{2}) + C
