Equation Solver

Solve equations

The calculator will try to find the roots (exact and numerical, real and complex), i.e. solve for $$$x$$$, $$$y$$$ or any other variable, of any equation (linear, quadratic, polynomial, rational, irrational, exponential, logarithmic, trigonometric, hyperbolic, absolute value) on the given interval.

Leave empty for autodetection.
If the interval is specified, the checkbox will be checked automatically.

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.

Your Input

Solve the equation $$$\left(x^{2} - 3 x - 2\right) \sin{\left(x \right)} = 0$$$ for $$$x$$$.


Real roots

$$$x = \frac{3}{2} - \frac{\sqrt{17}}{2}\approx -0.56155281280883$$$A

$$$x = \frac{3 + \sqrt{17}}{2}\approx 3.56155281280883$$$A

$$$x\in\left\{n \pi\; \middle|\; n \in \mathbb{Z}\right\}\approx \left\{3.141592653589793 n\; \middle|\; n \in \mathbb{Z}\right\}$$$

Complex roots

It seems that there are no complex roots.
