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

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

tan (x) + sec (x) + C

Solution steps

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

Expand

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

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

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

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

= tan (x) + sec (x)

Add a constant to the solution

= tan (x) + sec (x) + C

\int \frac{8 x}{( x ^{2} + 4 ) ^{3}} d x

\int x (1 + 2 ln (x)) d x

\int \frac{x - 3}{2 x x} d x

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

\int \frac{ln ( x )}{x ^{2}} d x
