Operation Manual

Chapter 2: Math, Angle, and Test Operations 41

Addition, Subtraction, Multiplication, 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. If you need to input

A/2, enter this as A

†1/2 or A †.5.

Note: For negation use

Ì. You will get an error if you use Ì and ¹ incorrectly.

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.

Power, Square, Square Root

You can use ^ (power, ›),

(square, ¡), and ‡( (square root, yC) with real and complex numbers,

expressions and lists. You cannot use ‡ with matrices.n.

Inverse

You can use

(inverse, œ) with real and complex numbers, expressions, lists, and matrices. The

multiplicative inverse is equivalent to the reciprocal, 1à
