It's kind of dumb question..(adsbygoogle = window.adsbygoogle || []).push({});

But, I just wanted to make sure.

Are Parseval's equality and Parseval's theorem same thing? (In terms of Fourier series)

i.e. do both mean [tex]\frac{1}{L}\int_c^{c+2L}|f(x)|^{2}dx = \frac{a_0^2}{2}+\sum_{n=1}^{\infty}[|a_n|^{2}+|b_n|^{2}][/tex]
