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
„[ α ]
„[ β ]
„[ γ
