Fourier series are used in the analysis of periodic functions A periodic function From the graph (or using our calculator), we can observe that: sin(nπ) = 0
introduction fourier series
The idea of Fourier series is that you can write a function as an infinite series of sines and cosines Do all this by hand, no graphing calculators, though if you
