Sexagesimal Decimal transformation

Sexagesimal notation is as follow

12 59 45.6

Represent 12 Degree, 59 Minutes, 45.6 Seconds

The calculator can preform the conversion between decimal and

sexagesimal numbers by [ ] and [ 2nd ] [ ]. See Example 29~30.

Coordinates transformation

Rectangular Coordinates

Polar Coordinates

x + y i = r (cos θ + i sin θ )

The calculator can perform the conversion between rectangular co- ordinates and polar coordinates by [ ALPHA ] [ Pol ( ] and [ ALPHA ] [ Rec ( ]. Calculation results are automatically stored in memory variables E and F. See Example 31~32.

(Note) :When using those key, make sure the calculator is set for the angle unit you want.

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 positive

 

integer x , where x69.

[ RANDOM ] Generates a random number between 0.000 and 0.999

Other functions ( x–1,,,, x2, x3, xy )

• The calculator also provides reciprocal ( [ x –1] ), square root ( []

), cubic root ( [ ] ), universal root [ ], square ( [ x 2 ] ), cubic ( [ x 3 ] ) and exponentiation ( [ x y ] ) functions. See Example 37~40.
