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,
mode it returns .5.
sin(value)
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.
