$\tan (y) = x$

Step 1

Take the inverse tangent of both sides of the equation to extract $y$ from inside the tangent.

$y = \arctan (x)$

Step 2

To rewrite as a function of $x$ , write the equation so that $y$ is by itself on one side of the equal sign and an expression involving only $x$ is on the other side.

$f (x) = \arctan (x)$
