Trigonometric Functions

Note all trigonometric data are radians (not degrees)

COSINE	cos(a) - cosine
SINE	sin(a) - sine
TANGENT	tan(a) - tangent
COTANGENT	ctan(a) - cotangent
ARCTANGENT	atan(a) - arctangent
ARCSINE	asin(a) - arcsine
ARCCOS	acos(a) - arccosine
ARCTAN2	atan2(y,x) - arctangent ⇒ y and x must be one dimensional signals; return one dimensional signal
