This joke is both good and bad.

I cant tell if I am laughing or crying

you’re doing both

fouriestseries:

Fourier series is a way to expand a periodic function in terms of sines and cosines. The Fourier series is named after Joseph Fourier, who introduced the series as he solved for a mathematical way to describe how heat transfers in a metal plate.

The GIFs above show the 8-term Fourier series approximations of the square wave and the sawtooth wave.

Mathematica code:

f[t_] := SawtoothWave[t]
T = 1; 
nmax = 18; 
a0 = (2/T)*Integrate[f[t], {t, -(T/2), T/2}]
anlist = Table[(2/T)*Integrate[f[t]*Cos[(2*Pi*n*t)/T], 
     {t, -(T/2), T/2}], {n, 1, nmax}]
bnlist = Table[(2/T)*Integrate[f[t]*Sin[(2*Pi*n*t)/T], 
     {t, -(T/2), T/2}], {n, 1, nmax}]
fs[t_, nmax_] := a0/2 + Sum[anlist[[n]]*Cos[(2*Pi*n*t)/T] + 
     bnlist[[n]]*Sin[(2*Pi*n*t)/T], {n, 1, nmax}]
Manipulate[Column[{Plot[{f[t], fs[t, nmax0]}, {t, -1, 1}, 
     PlotRange -> All, AxesLabel -> {"t", "f(t)"}, 
     PlotStyle -> {{Thick, Black}, {Thick, Red}}, 
     ImageSize -> 700, AspectRatio -> 1/2.8], 
     Row[{"f(t)=", fs[t, nmax0]}]}], {nmax0, 1, nmax, 1}]
