Coordinate conversion (Pol (x, y), Rec (r, θ))
l The results of the calculation are automatically assigned to variables
E and F.
Example 1.: To convert polar coordinates (r=2, θ=60°) to rectangular
coordinates (x, y) (DEG mode)
2 60
l , swaps displayed value with value in memory.
Example 2.: To convert rectangular coordinates (1, √3 ) to polar
coordinates
(r,
θ) (RAD mode)

l , swaps displayed value with value in memory.
Permutation
Example 1.: To determine how many different 4−digit values can be
produced using the numbers 1 through 7.
l Numbers cannot be duplicated within the same 4−digit value (1234 is
allowed, but 1123 is not).

Combination
Example 1.: To determine how many different 4−member groups can
be organized in a group of 10 individuals.
