Function sincosd_diff

Source
pub fn sincosd_diff(a: Degrees, b: Degrees) -> (UnitNegRange, UnitNegRange)
Expand description

Calculate the sine and cosine of an angle from the difference of a pair of values in Degrees.

Note: calculates the cosine of the angle from its sine and overrides the sine and cosine for ±30° and ±45° to their correct values.

  • a, b the angles in Degrees

returns sine and cosine of a - b as UnitNegRanges.
