Problem Statement[edit | edit source]

Page 491, #15,17. Plot the truncated Fourier series for n=2,4,8.

Solution[edit | edit source]

15.


Since , the function is odd.


After simplification,
. Using Equation (5) on page 490, the exapansion becomes;

With this becomes;
for n is "odd".
This means when n is even,



17.




 


Simplifying results in;

So,

 

when n is odd.

Simplifying results in;



Since for even n, becomes for even n.
