what are the equations for Triangular, square, sawtooth,

I know a sine wave it y=sin(X)

 

[CaptBubba]

I am pretty sure square is sin x + sin 2x + sin 3x+....... all the way up to infinity.

No, I'm pretty sure that's a pulse wave.

Square wave and triangle wave are about 2/3 down this page

Sawtooth appears to be on this page

(Sorry, to lazy to do the integrals on paper, and can't do it in my head like I used to.)

how would i go about entering these on a texas instruments Ti 80? What mode is x(t)?

does this have to do anything with fourier analysis?

 

[yage]

I thought Fourier analysis involved taking the Fourier transform of a function (switching from the time-domain to the frequency domain).

here's the stuff for square waves

and for sawtooth

The series of sinusoids used to create those sums are based on fourier analysis of the desired function.
