Fourier series expansion


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.


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.
