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
~~
deg#
minit#
~
@TITLE
@LVARI
~~
mitm#
msolvr
`
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

Example 2 - Any type of triangle
Opens the program symbol
Locks alphanumeric keyboard
Type in DEG (angular units set to DEGrees)
Type in MINIT_
Unlocks alphanumeric keyboard
List the name TITLE in the program
List the name LVARI in the program
Locks alphanumeric keyboard
Type in MITM_
Type in MSOLVR
Enter program in stack
The result is
