Division
You can use + (addition, Ã), N (subtraction, ¹), … (multiplication, ¯), and à (division, ¥)
with real and complex numbers, expressions, lists, and matrices. You cannot use à with
matrices.

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.
