Example 2 - Any type of triangle

Use a = 3, b = 4, c = 6. The solution procedure used here consists of solving

for all variables at once, and then recalling the solutions to the stack:

J @TRISO To clear up data and re-start MES

3[ a ] 4 [ b ] 6[ c ] To enter data

L To move to the next variables menu.

„ @ALL! Solve for all the unknowns.

‚ @ALL! Show the solution

The solution is:

At the bottom of the screen, you will have the soft menu keys:

@VALU @EQNS! @PRINT %%%% %%%% @EXIT

The square dot in @VALU indicates that the values of the variables, rather than

the equations from which they were solved, are shown in the display. To see

the equations used in the solution of each variable, press the @EQNS! soft menu

key. The display will now look like this:

The soft menu key @PRINT is used to print the screen in a printer, if available.

And @EXIT returns you to the MES environment for a new solution, if needed.

To return to normal calculator display, press J.

The following table of triangle solutions shows the data input in bold face and

the solution in italics. Try running the program with these inputs to verify the

solutions. Please remember to press J @TRISO at the end of each solution to

clear up variables and start the MES solution again. Otherwise, you may
