644 Mathematical Functions

The argument can be any floating point value or expression in radians.

The value of the Cosine function is always from –1 to +1, inclusive.

For example, the following expression is evaluated as 0.5 since the cosine

of 1.047 radians (60°) is 0.5.

Cosine(1.047)

To convert the argument of the Cosine function from degrees to radians,

multiply by

180

. For example, the following expression is evaluated as

0.5 (assuming the user constant Pi has been defined as the value of

)

since the cosine of 60° is 0.5.

Cosine(60 * Pi / 180)

Sine

The value of the Sine function is the sine of the argument angle (in

radians), as shown below.
