(Note) : When using those key, make sure the calculator is set for the
angle unit you want.
The calculator can perform the conversion between rectangular
coordinates and polar coordinates by [ 2nd ] [ P
R ] and [ 2nd ]
[ R

Probability
This calculator provides the following probability functions :
[ nPr ] Calculates the number of possible permutations of n item
taken r at a time.
[ nCr ] Calculates the number of possible combinations of n items
taken r at a time.
[ X! ] Calculates the factorial of a specified positive integer n ,
where n
≦
69.
