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,
y A) with real numbers, expressions, and lists. The current angle mode
setting affects interpretation.
Note:
The trig functions do not operate on complex numbers.
