Data can be entered by clicking the buttons or by pressing keys on the keyboard. All keys have keyboard equivalents; those key mappings that are not quite obvious (such as log) are documented in Table 3-1. Note that many of the functions are available only in Scientific mode (Table 3-2).

---|---|---|
Inv | i | Sets the inverse function for sin, cos, tan, Pl, x y , x 2 , x 3 , Ln, log, sum, and s. |
Hyp | h | Sets the hyperbolic function for sin, cos, and tan. |
F-E | v | Turns scientific notation on and off. Can only be used with decimal numbers. Numbers larger than 10 15 are always displayed with exponents. |
( ) | ( ) | Starts and ends a new level of parentheses. The maximum number of nested parentheses is 25. The current number of levels appears in the box above the ) button. |
dms | m | If the displayed number is in degrees, convert to degree-minute-second format. Use Inv + dms to reverse the operation. |
Exp | x | The next digit(s) entered constitute the exponent. The exponent cannot be larger than 289. Decimal only. |
Ln | n | Natural (base e) logarithm. Inv + Ln calculates e raised to the n th power, where n is the current number. |
sin | s | Sine of the displayed number. Inv + sin gives arc sine. Hyp + sin gives hyperbolic sine. Inv + Hyp + sin gives arc hyperbolic sine. |
x^y | y | x to the y th power. Inv + x^y calculates the y th root of x . |
Log | l | The common (base 10) logarithm. Inv + log yields 10 to the x th power, where x is the displayed number. |
Cos | o | Cosine of the displayed number. Inv + cosin gives arc cosine. Hyp + cosin gives hyperbolic cosine. Inv + Hyp + cosin gives arc hyperbolic cosine. |
x^3 | # | Cubes the displayed number. Inv + x^3 gives the cube root. |
n! | ! | Factorial of the displayed number. |
tan | t | Tangent of the displayed number. Inv + tan gives arc tan. Hyp + tan gives hyperbolic tan. Inv + Hyp + tan gives arc hyperbolic tan. |
x^2 | @ | Squares the displayed number. Inv + x^2 gives the square root. |
l/x | r | Reciprocal of displayed number. |
Pi | p | The value of pi (3.1415...). Inv + Pi gives 2 x pi. |
