Hi. I'm new with Mathematica and would like to know where my coding is wrong using Manipulate and Plot functions:
This Expression works fine:
Manipulate[ExpToTrig[FourierSeries[Cosh[x], x, N]], {N, 1, 10, 1}]
However, when I try to use Manipulate to plot the Fourier Series, it does not plot anything:
Manipulate[Plot[ExpToTrig[FourierSeries[Cosh[x], x, N]], {x, -3, 3}], {N, 1, 10,1}]
Thank you.
Andre
