Example 1: To convert polar coordinates ( r = 2, θ = 60°) to rectangular
coordinates (
x , y ) (Angle unit: Deg)
x = 1

Example 2: To convert rectangular coordinates (1, √
3) to polar
coordinates ( r , θ ) (Angle unit: Rad)
r = 2

Factorial (!)
This function obtains the factorials of a value that is zero or a positive
integer.
Example: (5 + 3)! = 40320
5 3 ( x !)
40320.
Random Number (Ran#)
Function that generates a pseudo random number in the range of 0.000 to
0.999.
Example: Generate three 3-digit random numbers.
The random 3 digit decimal values are converted to 3-digit integer values
by multiplying by 1000.
Note that the values shown here are examples only. Values actually
generated by your calculator will be different.
1000 (Ran#) 634.
33
