2-4 Math, Angle, and Test Operations
The most commonly used math functions are on the keyboard. The keyboard
math operations can be used with decimal numbers, fractions (except as noted),
expressions, and lists.
The basic arithmetic functions are: addition «, subtraction |,
multiplication p, and division e. Each argument for these
functions can be a list.
valueA+valueB, valueAìvalueB,
valueA×valueB, valueAàvalueB
The trigonometric functions are interpreted according to the
current RADIAN/DEGREE mode setting. (Refer to page 1-9 for
instructions on changing the mode setting.) For example,
SIN 30 in RADIAN mode returns L.9880316241; in DEGREE
mode, it returns .5. Each argument for the trigonometric
functions may be a list.
SIN value, COS value, TAN value
SINê, COSê, and TANê are the inverse trig functions (arcsine,
arccosine, and arctangent).

ê (inverse, V) may be used with numbers, expressions, or
lists. The multiplicative inverse is the equivalent of the
reciprocal, 1àx.
