Fourier series expansion

Description

The following simulation shows the partial sum (up to 20 terms) of the Fourier series for a given function defined on the interval [a,b]. You can also check your calculations by entering the coefficients a0, a1 and b1.

Instructions:

Change the function and calculate its Fourier series. Then type the correct values of the terms a0, a1 and b1, rounded to two decimal places. Remark: Activate the box Fourier series and increase, or decrease, the number of terms in the partial sum.
