Trigonometric Polynomials....(adsbygoogle = window.adsbygoogle || []).push({});

It's too difficult to understand.....

Please tell me how a complex trigonometric polynomial works. I think real trigonometric polynomial is good enough.

[tex]T_{N}=\sum^N_{n=0}a_n cos(nx) +i\sum^N_{n=0}a_n*sin(nx)[/tex]

[tex]T_{N}[/tex] is postion at time x of an object moving along a line. seems have nothing to do with complex numbers.
