Trigonometric / Inverse-Tri. Functions

The calculator provides standard trigonometric functions and inverse
trigonometric functions - sin, cos, tan, sin
Example 35~37.
(Note) : When using those keys, make sure the calculator is set
for the angle unit you want.

Hyperbolic / Inverse-Hyp. Functions

The calculator uses [ 2nd ] [ HYP ] to calculate the hyperbolic
functions and inverse- hyperbolic functions – sinh, cosh, tanh,
–1 –1
sinh , cosh and tanh
(Note) : When using those keys, make sure the calculator is set
for the angle unit you want.

Coordinates Transformation

Pressing [ 2nd ] [ R
coordinates to polar coordinates or vice versa.
40~41.
Rectangular Coordinates
(Note) : When using those key, make sure the calculator is set
for the angle unit you want.

Probability

Pressing [ PRB ] displays the probability menu. See Example
42~46. With the following functions :
Calculates the number of possible permutations of n item
nPr
taken r at a time.
nCr Calculates the number of possible combinations of n
items taken r at a time.
! Calculates the factorial of a specified positive integer n ,
where n ≦ 69.
Generates a random number between 0 and 1.
RANDM
RANDMI Generates a random integer value between two specified
integers, A and B, where A ≦ random value ≦ B
