13.Key in U (the x–coordinate in the new system) and press f.

14.Key in V (the y–coordinate in the new system) and press fto see X.

15.Press fto see Y.

16.For another new–to–old transformation, press fand go to step 13. For an old–to–new transformation, go to step 7.

Variables Used:

 

M

The x–coordinate of the origin of the new system.

N

The y–coordinate of the origin of the new system.

T

The rotation angle, θ, between the old and new systems.

X

The x–coordinate f a point in the old system.

Y

The y–coordinate of a point in the old system.

U

The x–coordinate of a point in the new system.

V

The y–coordinate of a point in the new system.

Remark:

 

For translation only, key in zero for T. For rotation only, key in zero for M and N.

Example:

For the coordinate stems shorn below, convert points P1, P2 and P3,which are currently in the (X, Y) system, to points in the (X', Y') system. Convert point P'4, which is lid the (X',Y') system, to the (X,Y) system.
