Tangent Calculator

Calculate the tangent of a number

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.

Your Input

Find $$$\tan{\left(\frac{\pi}{8} \right)}$$$.


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