# Polynomial integral

The calculator integrates a univariate polynomial and calculates an integration constant by a point.

This calculator integrates a polynomial function. In addition, it calculates the integration constant if you provide a point lying on the graph of the result function.

Result

An indefinite integral of a polynomial function defined by the coefficients a0 .. an, can be calculated by the formula below:
$I(x) = \int{\sum_{i=0}^n{a_i x^i}}=\sum_{k=1}^{n+1}{\frac{a_{k-1} x^k}{k}}+C$
If you know point coordinates (x0,y0) , belonging to the result function graph, you can calculate the integration constant С in the following way:
$C = y_0-\left(\sum_{k=1}^{n+1}{\frac{a_{k-1} x_0^k}{k}}\right)$
