# 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 a_{0}, a_{1}and b_{1}.## Instructions:

Change the function and calculate its Fourier series. Then

**type the correct**values of the terms a_{0}, a_{1}and b_{1}, rounded to two decimal places.**Remark:**Activate the box**Fourier series**and increase, or decrease, the number of terms in the partial sum.## New Resources
