A Performing Calculation with a Built-in Formula

The following example shows how to use Heron’s formula to determine the area of a triangle when the lengths of its three sides (8, 5, 5) are known.

Operation Procedure

b

Search for Heron’s formula:

G)(H)c(HeronFormula)

Start the calculation:

E (This displays a prompt for input of the first variable value.)

Input a = 8, b = 5, and c = 5:

8E5E5E

E (This displays the calculation result.)

As shown above, the calculation result appears after you assign values to all of the required variables.

In the case of a formula that produces multiple results (such as /Y Conversion), the Q symbol will turn on when the first calculation result is on the display. Press E to display the other result(s) produced by the formula. The Q symbol will turn off when the final result is on the display.

Pressing E while the final calculation result is on the display (Q symbol turned off) will re-execute the formula from the beginning.
