2-4 Function Calculations

kFunction Menus

This calculator includes five function menus that give you access to scientific functions not printed on the key panel.

•The contents of the function menu differ according to the mode you entered from the Main Menu before you pressed the Kkey. The following examples show function menus that appear in the RUN • MAT mode.

uHyperbolic Calculations (HYP)

[OPTN]-[HYP]

•{sinh}/{cosh}/{tanh} ... hyperbolic {sine}/{cosine}/{tangent}

•{sinh–1}/{cosh–1}/{tanh–1} ... inverse hyperbolic {sine}/{cosine}/{tangent}

uProbability/Distribution Calculations (PROB)

[OPTN]-[PROB]

•{x!} ... {press after inputting a value to obtain the factorial of the value.}

•{nPr}/{nCr} ... {permutation}/{combination}

•{Ran#}... {pseudo random number generation (0 to 1)}

•{P(}/{Q(}/{R(} ... normal distribution probability {P(t)}/{Q(t)}/{R(t)}

•{t(} ... {value of normalized variate t(x)}

uNumeric Calculations (NUM)

[OPTN]-[NUM]

•{Abs} ... {select this item and input a value to obtain the absolute value of the value.}

•{Int}/{Frac} ... select the item and input a value to extract the {integer}/{fraction} part.

•{Rnd} ... {rounds off the value used for internal calculations to 10 significant digits

(to match the value in the Answer Memory), or to the number of decimal places (Fix) and number of significant digits (Sci) specified by you.}

•{Intg} ... {select this item and input a value to obtain the largest integer that is not greater than the value.}

•{RndFi} ... {rounds off the value used for internal calculations to specified digits (0~9) (see page 2-1-3).}
