– 6 = 0
Keys:
(In RPN mode)
Display: Description:
t
P
value
Starts the polynomial root finder;
prompts for order.
2
¥
value
Stores 2 in
F
; prompts for
B
.
1
¥
value
Stores 1 in
B
; prompts for
A
.

z¥
Stores –6 in
A
; calculates the first
root.
¥
Calculates the second root.
Coordinate Transformations
This program provides two–dimensional coordinate translation and rotation.
The following formulas are used to convert a point P from the Cartesian coordinate
pair (
x, y
) in the old system to the pair (
u
,
v
) in the new, translated, rotated system.
u
= (
x
–
m
) cos
θ
+ (
y
–
n
) sin
θ
v
= (
y
–
n
) cos
θ
–(
x
–
m
) sin
θ
The inverse transformation is accomplished with the formulas below.
x
=
u
cos
θ
–
v
sin
θ
+
m
y
=
u
sin
θ
+
v
cos
θ
+
n
The HP 33s complex and polar–to–rectangular functions make these computations
straightforward.
