Start the multiple equation solver by pressing J@SOLVE. The calculator

produces a screen labeled , "vel. & acc. polar coord.", that looks as follows:

To enter the values of the known variables, just type the value and press the

button corresponding to the variable to be entered. Use the following

keystrokes: 2.5 [ r ] 0.5 [ rD ] 1.5 \ [ rDD ] 2.3 [ θD ] 6.5 \ [ θDD ].

Notice that after you enter a particular value, the calculator displays the

variable and its value in the upper left corner of the display. We have now

entered the known variables. To calculate the unknowns we can proceed in

two ways:

a). Solve for individual variables, for example, „[ vr ] gives vr: 0.500.

Press L„[ vθ ] to get vθ : 5.750 , and so on. The remaining results

are v: 5.77169819031; ar: -14.725; aθ: -13.95; and a:

20.2836911089.; or,

b). Solve for all variables at once, by pressing „@ALL!. The calculator will

flash the solutions as it finds them. When the calculator stops, you can

press ‚@ALL! to list all results. For this case we have:

Pressing the soft-menu key @EQNS will let you know the equations used to

solve for each of the values in the screen:
