# Tangent Calculator

The calculator will find the tangent of the given value in radians or degrees.

The tangent $y=\tan(x)$ is such a function that $y=\frac{\sin(x)}{\cos(x)}$.

The domain of the tangent is $x \ne \frac{\pi}{2} + \pi n, n \in \mathbb{Z}$, the range is $(-\infty,\infty)$.

It is an odd function.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Find $\tan{\left(\frac{\pi}{8} \right)}$.
$\tan{\left(\frac{\pi}{8} \right)} = \tan{\left(\left(\frac{45}{2}\right)^0 \right)} = -1 + \sqrt{2}\approx 0.414213562373095$A
