Description
Prompts for and stores V.
Pushes V up and recalls U.
Pushes U and V up and recalls T.
Sets radius to 1 for the computation of sin(T) and cos(T).
θ
Calculates cos(T) and sin(T).
Calculates U cos(T) –V sin(T) and U sin(T) + V cos(T).
Pushes up previous results and recalls N.
Pushes up results and recalls M.
Completes calculation by adding M and N to previous
results.
Stores the x–coordinate in variable X.
Swaps the positions of the coordinates.
Stores the y–coordinate in variable Y.
Swaps the positions of the coordinates back.
Halts the program to display X.
Halts the program to display Y.
Goes back for another calculation.

Program Instructions:
1. Key in the program routines; press
Å
when done.
2. Press
t
D to start the prompt sequence which defines the coordinate
transformation.
3. Key in the x–coordinate of the origin of the new system M and press
¥
.
4. Key in the y–coordinate of the origin of the new system N and press
¥
5.
Key in the rotation angle T and press
¥
.
6. To translate from the old system to the new system, continue with step 7. To
translate from the new system to the old system, skip to step 12.
