Kcoordinate Conversion (Pol(X, Y), Rec (R, Θ )); Kpermutation; Kcombination - Casio fx-350TL User Manual

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,
to rectangular coordinates (x, y) (DEG mode)

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

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