# Area between curves online calculator

Plane curve area calculations is one of the main applications of definite integral.

To get an area of the plane curve depicted in figure, one need to calculate definite integral of the form:

Functions f(x) and g(x) as a rule are known from a problem situation, abscisses of their cross points x=a and x=b need to be calculated. To do this one need to solve equation of the type:

f(x)
=
g(x)
<=>
{
x_{1}=a,
x_{2}=b
}

Online area calculator based on Wolfram Alpha capable to calculate area between two crossed curves.
