# Fourier series - Example 1

The following simulation shows the partial sum of the Fourier series for a given function (defined below). But this is

**NOT CORRECT**, since the terms a_{0}, a_{1}and b_{1}are*missing or wrong*. Calculate the Fourier series of the function and then**type the correct**values of the terms a_{0}, a_{1}and b_{1}, rounded to two decimal places, to show the correct partial sum of the Fourier series expansion. Click on the buttons to increase, or decrease, the number of terms in the partial sum.## New Resources
