Question

in parseval 's relation of half range fourier cosine series expansion, which of the following terms doesn't appear​

Answer 1

Answer:

As the function is considered to be an even function, bn term becomes a null value as the integral becomes zero. So, only bn doesn't appear in the parseval's relation of half range Fourier cosine series.

Answer 2

Answer: bn terms doesn't appear​

Step-by-step explanation:

• The explanation is: In the expansion of a function in half range Fourier cosine series, only an and a0 appear.
• As the function is considered to be an even function, bn term becomes a null value as the integral becomes zero.
• So, only bn doesn’t appear in the parseval’s relation of half range Fourier cosine series.
