E and F.
Example 1.: To convert polar coordinates (r=2, θ=60°) to rectangular
coordinates (x, y) (DEG mode)
x

y
, swaps displayed value with value in memory.

Example 2.: To convert rectangular coordinates (1, √3 ) to polar
coordinates
(r, θ) (RAD mode)
r

Permutation

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

Combination

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