Example 2: T
o convert rectangular coordinates (1, √
3) to polar
coordinates ( r , θ ) (Angle unit: Rad)
fx-82MS/fx-85MS/fx-300MS/fx-350MS:
r = 2
1 3 2.
θ = 1.047197551
(F) 1.047197551
Press (E) to display the value of r , or (F) to display the
value of θ .
fx-220 PLUS:
r = 2
1 (,) 3 2.
θ = 1.047197551
( y , θ )
1.047197551
Press ( x , r ) to display the value of r , or ( y , θ )
to display the value of θ .
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.
