Coordinates transformation
Rectangular Coordinates
Polar Coordinates
x + y i = r (cos
θ
+ i sin
θ
)
(Note) : When using those keys, 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 P ]. See Example 31~32.
Probability
This calculator provides the following probability functions (See
Example 33~36.):
[ 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 integer n , where n
≦
69.
[
RANDM
] Generates a random real number between 0.000 and
0.999.
Division with Quotient and Remainder
You can use [ 2nd ]
[ ÷
R ] to get the quotient and remainder of
division operations. Only the quotient is stored to Answer memory.
(See Example 37)
(Note) : If one of the following conditions are present when
performing an operation with calculation and display of
remainder, the calculation will be treated as a normal
division (without calculation or display of remainder)
A. When the dividend when the divisor is a great value.
Example: 20000000000 [ 2nd ] [ ÷R ] 17 [=]
is calculated as: 200000000000 ÷ 17
B. When the quotient is not a positive value or the
remainder is not an entire positive or a positive fraction
Example: [(-)] 5 [ 2nd ] [ ÷R ] 2 [=]
is calculated as: -5 ÷ 2
