Is correct to define fourier series like:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]f(t)=\sum_{k=0}^{\infty}a_k \cos \left (\frac{2 \pi k t}{T} \right ) + b_k \sin \left (\frac{2 \pi k t}{T} \right )[/tex]

Where ak and bk:

[tex]a_k=\frac{1}{T} \int_{-T}^{+T} f(t) \cos \left (\frac{2 \pi k t}{T} \right ) dt[/tex]

[tex]b_k=\frac{1}{T} \int_{-T}^{+T} f(t) \sin \left (\frac{2 \pi k t}{T} \right ) dt[/tex]
