Trigonometric functions are used to calculate angles between members or inside custom components and are used in angle attributes. The unit of angle for trigonometric functions is given with the prefixes:
d is degree (values 0-360).
r is radians (this is the default, values 0-2 π).
g is gradient (grad, values 0-400).
For example:
sin (d180)
sin (r3.14) or sin (3.14)
sin (g200)
You can access trigonometric functions in the Formula Contents dialog box and in the Rule Contents dialog box.
Select functions from the Math list in the Operators area of the dialog box.
