Tangent:

The tangent is the ratio of the adjacent side over the opposite side
a
tan A= . The tangent repeats itself every p radians and has a range from
b
-∞ to ∞. The tangent has this range because when the angle approaches
½p radians the opposite side gets very small and will actually be zero when
the angle is ½p radians.

Degrees Function:

The degrees() function does the quick mathematical calculation to convert
an angle in radians to an angle in degrees. The formula used is
degrees=radians/ 2∗360 .

Radians Function:

The radians() function will convert degrees to radians using the formula
radians=degrees/360∗2 . Remember all of the trigonometric functions in
BASIC-256 use radians and not degrees to measure angles.
