- Fourier cosine series

I was just going through my old notes on this i.e

The concept is straight forward- only challenge phew is the integration bit...took me round and round a little bit... that is for ##A_n## part.

My working pretty ok i.e we shall realize the text solution. Kindly find my own working below.

Now to my question supposing we have to find say Fourier cosine series for ##f(x)= x^7##. The integration by parts here will take like forever to do. Do we have software for this? Will Wolfram help?
