GraphCalc supports all of the trigonometric function: Sin, Cos, Tan, ArcSin, ArcCos, ArcTan, HypSin, HypCos, and HypTan. They may be used in both an expression and in an equation to be graphed. They are entered just as they are said, with the operator first. For example:

• sin (2pi)

• tan (x)

• hypcos (x^2)
