Fourier Series Function Guess
Description
For this applet you set the Fourier Series Coefficients and then guess the function.
The domain is -L<x<L . The slider controls the number of terms to sum. For the coefficients you can enter a function containing n and optionally L . The coefficients should get smaller as n increases.The solid blue curve shows the Fourier Series partial sum and the dashed green curve shows your guess at the function.
