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
f
to see
X
.
15.
Press
f
to see
Y
.
16.
For another new–to–old transformation, press
f
and 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
P
1
,
P
2
and
P
3
,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.
