Trigonometry Calculations

Before using the trigonometric functions (except hyperbolic calculations), select the appropriate angle

unit (Deg/ Rad/ Gra) by .

90o = Radians = 100 Gradients. (Example #12)

Permutation, Combination, Factorials and Random Number Generation

• Permutation : nPr = (Example #13)

• Combination : nCr = (Example #13)

• Factorial

: x! = x(x-1)(x-2).....(2)(1) (Example #13)

Random Number Generation (Example #14)

: To generate a random number between 0.000 and 0.999.

: To generate a random number between two specified positive integers. The entry is divided by " , ".

* The value is show in Ex. #14 only a sample, results will differ each time.

Least Common Multiple and Greatest Common Divisor

LCM: Calculate the least common multiple among

(maximum) three positive integers.

GCD: Calculate the greatest common divisor among (maximum) three positive integers. (Example #15)

Quotient & Remainder

"Quotient" (Q) is the result of a division problem, "Remainder" (r ) is the value left in an integer division problem.

The calculated quotient value (Q) and remainder value

(r)will be stored into memory variables "C" and "D" automatically assigned. (Example #16)

!Only Quotient Value (Q) can continue to be used for the next calculation or being stored into memory variables.
