Math, Angle, and Test Operations 2-3
Math operations that are valid for lists return a list
calculated element by element. If you use two lists in the
same expression, they must be the same length.
You can use + (addition, Ã), N (subtraction, ¹), ä
(multiplication, ¯), and à (division, ¥) with real and
complex numbers, expressions, lists, and matrices. You
cannot use à with matrices.

valueAävalueB valueA à valueB
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.
sin(value) cos(value) tan(value)
You can use the inverse trig functions (arcsine, y [SINL1];
arccosine, y [COSL1]; and arctangent, y [TANL1]) with
real numbers, expressions, and lists. The current angle
mode setting affects interpretation.
sinL1(value) cosL1(value) tanL1(value)
Note: The trig functions do not operate on complex numbers.
You can use ^ (power, ›), 2 (square, ¡), and ‡( (square
root, y [‡]) with real and complex numbers, expressions,
lists, and matrices. You cannot use ‡( with matrices.

You can use L1 (inverse, —) with real and complex
numbers, expressions, lists, and matrices. The
multiplicative inverse is equivalent to the reciprocal, 1àx.
