Graphing fourier series to get square waves and sawtooth waves on Google.
Did you know that Google will graph functions for you. I played around with fourier series to make sawtooth waves and square waves just to see what it looked like.
Sawtooth - just copy and paste into google search.
2/pi(sin(x)+sin(2x)/2+sin(3x)/3+sin(4x)/4+sin(5x)/5+sin(6x)/6+sin(7x)/7+sin(8x)/8+sin(9x)/9+sin(10x)/10+sin(11x)/11+sin(12x)/12)
Square Wave- just copy and paste into google search
4/pi(sin(2x)+sin(6x)/3+sin(10x)/5+sin(14x)/7+sin(18x)/9+sin(22x)/11+sin(26x)/13+sin(30x)/15+sin(34x)/17+sin(38x)/19)
Sawtooth - just copy and paste into google search.
2/pi(sin(x)+sin(2x)/2+sin(3x)/3+sin(4x)/4+sin(5x)/5+sin(6x)/6+sin(7x)/7+sin(8x)/8+sin(9x)/9+sin(10x)/10+sin(11x)/11+sin(12x)/12)
Square Wave- just copy and paste into google search

Fun with graphing.
