# Euler's Method

Euler's method lets us construct antiderivatives numerically.
At a series of points, (x,y), I find the value of the function, and multiply by the width, , to get the change in height, . The next point is .
This is building an antiderivative using the left hand rule.
The initial point and the value of the change in x are both controlled by sliders.
