Fourier series expansion of f(x)=|cosx| in the interval -π to π.
Показать описание
In this video, I have shown how to get the Fourier series expansion for f(x)=|cosx| in the interval of -π to π. |cosx| is an even function, and therefore, we have only obtained the a_0 and a_n terms.
**Books I recommend for Fourier Series Analysis:**
1) Mathematical Methods for Physicists by Weber, Arfken
2) Higher Engineering Mathematics by B. S. Grewal
3) Mathematical Physics by P. K. Chattopadhyay
*Prepare for NET/GATE (physics)*
Hey! I have made this video using the Samsung Galaxy S6 tab. It's highly recommended to use. If you are a grad student you can have this pocket-friendly one. You can use a cool keyboard alongside, which will facilitate ease of working.
