Keyboard Math Operations Using Lists with Math Operations 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. 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. valueA+valueB valueA...valueB valueA N valueB valueA à valueB 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. sin(value) cos(value) tan(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. sinL1(value) cosL1(value) tanL1(value) Note: The trig functions do not operate on complex numbers. Power, Square, Square Root You can use ^ (power, ›), 2 (square, ¡), and ‡( (square root, y C) with real and complex numbers, expressions, lists, and matrices. You cannot use ‡( with matrices.
