Fourier Series 3/3

Описание к видео Fourier Series 3/3

Extending the period of the Four­i­er Series from 2π to 2L.

Units of the Four­i­er Series.

Basis vec­tors and func­tions.

Writ­ing the func­tion in terms of cosines and sines. I.e., using
cosine and sines as ‘basis func­tions’ for our ‘space’.

Why cosine is an ‘even’ func­tion and that sine is an ‘odd’ func­tion.

Look­ing at the ‘par­ity’ (even­ness or oddness) of the Four­i­er Series components.
