Function Calculations

This section explains how to use the calculator’s built-in functions.

The functions available to you depends on the calculation mode you are in.The explanations in this section are mainly about the functions that are available in all calculation modes. All of the examples in this section show operation in the COMP Mode (N1).

•Certain function calculations may take some time to display calculation results. Before performing an operation, be sure to wait until execution of the current operation is complete.You can interrupt an ongoing operation by pressing A.

kPi (π) and Natural Logarithm Base e

You can input pi (π) or natural logarithm base e into a calculation. The following shows the required key operations and the values this calculator uses for pi (π) and e.

π = 3.14159265358980 (15(π)) e = 2.71828182845904 (S5(e))

•You can use π and e in any calculation mode except for BASE-N.

k Trigonometric and Inverse Trigonometric

Functions

•Trigonometric and inverse trigonometric functions can be used in the COMP, STAT, EQN, MATRIX, TABLE, and VECTOR calculation modes. They can also be used in the CMPLX Mode, as long as complex numbers are not used for their arguments.

•The angle unit required by trigonometric and inverse trigonometric functions is one specified as the calculator’s default angle unit. Before performing a calculation, be sure to specify the default angle unit you want to use. See “Specifying the Default Angle Unit” for more information.

Appendix <#018> sin 30 = 0.5, sin–10.5 = 30

k Hyperbolic and Inverse Hyperbolic

Functions

Hyperbolic and inverse hyperbolic functions can be used in the same modes as the trigonometric functions. Pressing the wkey displays a menu of functions. Press the number key that corresponds to the function you want to input.
