This is a calculator which computes the definite and indefinite integrals (antiderivative) of a function with respect to a variable x.

## Integral Calculator

The calculator will computes an integral of given function. To solve definite integrals you need to provide values for upper and lower bound. Important: The form will NOT let you enter illegal characters (like y, z, ;, ...)

 Solve indefinite integral (default) Solve definite integral Lower Bound = Upper Bound = Note: For lower and upper bound you can input: decimals (10.2) or fractions (-7/4). You can use -inf, inf, pi and e too. Example: $-\frac{4}{9}+2\pi$ = - 4/9 + 2pi

## Examples of valid and invalid expressions

 Function to integrate Correct syntax is Incorrect syntax is $$(2x+1)^6$$ (2x+1)^6 [2x+1]^6 $$\frac{10x + 1}{x^2-4}$$ (10x+1)/(x^2-4) 10x+1/x^2-4 $$\left(ln(x)\right)^2$$ ln(x)^2 ln^2(x) $$x ~ ln\left(\frac{x-1}{x+1}\right)$$ x*ln((x-1)/(x+1)) x*ln(x-1)/(x+1)
