Using the trig functions

The Trig list contains the following functions:

Function Abbreviation Description

Cosine Cos(x) Returns the cosine of x

Sine Sin(x) Returns the sine of x

Tangent Tan(x) Returns the tangent of x

Arc cosine ArcCos(x) Returns the inverse cosine (arc cosine) of x

Arc sine ArcSin(x) Returns the inverse sine (arc sine) of x

Arc tangent ArcTan(x) Returns the inverse tangent (arc tangent) of x

Examples

5cos(.5)

y(x) = sin(x–π/2)

Changing the measured angle

By default, trigonometric arguments are interpreted as radians. To use degrees

or gradients, follow these steps:

1 Tap measured angle.

2 Tap the desired measurement from the list.

Graphs and tables are updated automatically when you change the angle. Results in

the math window are not automatically updated.
