FractSineCosine

You can use the FractSineCosine function to obtain both the sine and cosine of an angle measured in degrees.

fract FractSineCosine (Fixed degrees, fract *cosine);

degrees

The angle in degrees for which the cosine and sine are required.

cosine

A pointer to the location where the cosine of the angle is required.

function result

The sine of the angle specified.

DESCRIPTION

Given the degrees parameter in degrees, the FractSineCosine function returns the sine as the function result and the cosine in the cosine parameter. Values for the degrees parameter are specified in degrees, not radians. The range of the angle is -32,768 to +32,769.999 degrees.
