The argument may be any floating point value or expression in radians.
The value of the

Sine

function is always from –1 to +1, inclusive.

For example, the following expression is evaluated as 0.5 since the sine of
0.5235 radians (30°) is 0.5.

Sine(0.5235)

To convert the argument of the

Sine

function from degrees to radians,

multiply by

180

. For example, the following expression is evaluated as

0.5 (assuming the user constant

has been defined as the value of

)

since the sine of 30° is 0.5.

Sine(30 * Pi / 180)

Tangent

The value of the Tangent function is the tangent of the argument angle (in
radians), as shown below.
