Programming the MES triangle solution using User RPL

To facilitate activating the MES for future solutions, we will create a program

that will load the MES with a single keystroke. The program should look like

this: << DEG MINIT TITLE LVARI MITM MSOLVR >>, and can be typed in

by using:

‚å Opens the program symbol

~~ Locks alphanumeric keyboard

deg# Type in DEG (angular units set to DEGrees)

minit# Type in MINIT_

~ Unlocks alphanumeric keyboard

@TITLE List the name TITLE in the program

@LVARI List the name LVARI in the program

~~ Locks alphanumeric keyboard

mitm# Type in MITM_

msolvr Type in MSOLVR

` Enter program in stack

Store the program in a variable called TRISOL, for TRIangle SOLution, by

using: ³~~trisol` K

Press J, if needed, to recover your list of variables. A soft key label

@TRISO should be available in your menu.

Running the program – solution examples

To run the program, press the @TRISO soft menu key. You will now have the

MES menu corresponding to the triangle solution. Let’s try examples of the

three cases listed earlier for triangle solution.

Example 1 – Right triangle

Use a = 3, b = 4, c = 5. Here is the solution sequence:

3[ a ] 4 [ b ] 5[ c ] To enter data

„[ α ] The result is

α: 36.8698976458

„[ β ] The result is β: 53.1301023541.

„[ γ ] The result is γ:

90.
