Graphing Examples

Graphing Sine & Cosine

Square Wave with Random Noise

Input	SIGN(sin(x)) + 0.2 * Ran# - 0.1
Range	0; 3
Angle Mode	Cycles
No. Points	100
Notes	The SIGN function converts sine into a square wave, while Ran# adds "noise". The noise will change each time you plot the function.

Graphing an Asymptote

Graphing an Asymptote

Input	1 / x
Range	-10; +10
Angle Mode	N/A
Interval	0.5
Notes	Use "Interval", not "No. Points" so as to create a discontinuity at x = 0 (i.e. 1 / 0 -> INFINITY).
