Function Calculations

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

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.

Pressing twill display a menu of functions that you can use to select the one you want to input. You can also use a direct key operation to input the following functions.

FC-200VRnd(, sin(, cos(, tan(, x2, '(, ^(, e^(, ln(FC-100VRnd(, sin(, cos(, tan(, e^(, 10^(, ^(, ln(, log(, x'(

All calculations in this section are performed in the COMP Mode (g).

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))

kTrigonometric and Inverse

Trigonometric Functions

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 “Configuring Settings” (page E-16) for more information.
