Trigonometric Functions

You can use the trigonometric (trig) functions (sine, ˜; cosine, ™; and tangent, š)

with real numbers, expressions, and lists. The current angle mode setting affects

interpretation. For example,

sin(30) in Radian mode returns L.9880316241; in Degree

mode it returns .5.

You can use the inverse trig functions (arcsine, y?; arccosine, y@; and

arctangent, yA) with real numbers, expressions, and lists. The current angle mode

setting affects interpretation.

Note: The trig functions do not operate on complex numbers.
