Equation Solver

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.

Enter an equation:
Like x^2+3x+4=0 or sin(x)=x.
Find the solution with respect to:
Enter an interval: ,
Leave empty, if you don't have any restrictions.
Only real roots will be searched for if you specify the interval, regardless of whether the box is checked.

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.
