Riemann Sum Example

In this example, we are numerically approximating the value of
$\displaystyle \int_a^b f(x) \, dx$
by using different approximation schemes.

You can change the function, the bounds, and the numerical scheme below.
Also, if you click on the slider and drag, the number of subdivisions for the
approximation will increase, thus yielding a better approximation. 

f(x) =     a:    b:
