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–/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.
