k Coordinate Conversion (Pol(x, y), Rec (r, θ ))
•Calculation results are automatically assigned to vari-
ables E and F.
• Example 1: To convert polar coordinates (r2,
 60°)
to rectangular coordinates (x, y) (DEG mode)
x A F 2 P 60 T =
y 0 o
• 0 n, 0 o swaps displayed value with value in
memory.
• Example 2: To convert rectangular coordinates (1, 3)
to polar coordinates (r,
 ) (RAD mode)
r
f 1 P L 3 T =
θ 0 o
• 0 n, 0 o swaps displayed value with value in
memory.
k Permutation
• Example: To determine how many different 4-digit val-
ues can be produced using the numbers 1 through 7
•Numbers cannot be duplicated within the same 4-digit
value (1234 is allowed, but 1123 is not).

• Example: To determine how many different 4-member
groups can be organized in a group of 10 individuals
