Graphing calculator
 

I realized I could do this, and I thought it would be rather neat to have one, so I wouldn't have to dig out my ti-89 every time I wanted to see a graph.

It is nothing spectacular, but let me save you all the trouble :)

I commented fairly well. If you understand parametric equations you will have no problem understanding this.

Edit: This is version 2 of the NPC. It can now handle x!=t, as well as adding a few new easy things to manipulate.

Here is the graph precoded into it. y=sin(t),x=t

Here is another one

x=t
y=t^2

I will finagle with it and put up one in which x!=t later.

Parametric equations with x!=t now work.

x=5*cos t
y=5*sin t

As do piecewise functions, to an extent.

x=t
y=(int(this.t/2)==this.t/2?3:0)

Pretty neat.

Thanks, now I can use graal for school work.

It'd work if you didnt connect the dots

Yeah I know, but I didn't feel like going through the trouble of finding all the discontinuities.

At Kai's suggestion, I would like to let you know that if you are interested, you can throw a sleep .05 (Shh! Kai, that was a preemptive Shh!) at the end of the for loop and the graphs will animate.

Thats only ten seconds dude.

Creative ;)
