θ
8T
´
¸8º
Calculates cos(T) and sin(T).
%º

Program Instructions:
1.
Key in the program routines; press
when done.
2. Press
X
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
g
.
4. Key in the y–coordinate of the origin of the new system N and press
g
5. Key in the rotation angle T and press
g
.
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.
