Sample Equations:

The following are a few examples of equations you can plot.

Mathematical Expression	Way of typing in graph plotter
y = 2x	y = 2*x
y = x² + 3x - 2	y = x^2 + 3*x - 2
y = sin(x)	y = sin(x)
y = tan²(x)	y = (tan(x))^2
y = cos³(x) + 2	y = (cos(x))^3 +2
y = sin(tan(x)) + (x/2)	y = sin(tan(x))+ (x/2)
y = arctan(x)	y = atn(x)
