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 ]
