$\int \frac{\sin (x)}{\cos (x)} d x = \int - \frac{1}{u} d u$

Step 1

This integral could not be completed using u-substitution. Mathway will use another method.

Step 2

Convert from $\frac{\sin (x)}{\cos (x)}$ to $\tan (x)$ .

$\int \tan (x) d x$

Step 3

The integral of $\tan (x)$ with respect to $x$ is $\ln (| \sec (x) |)$ .

$\ln (| \sec (x) |) + C$
