u invHypergeoCDf [Action][Distribution/Inv.Dist][Inverse][invHypergeoCDf]
Function: Returns the minimum number of trials of a hypergeometric cumulative distribution for specified
values.
Syntax: invHypergeoCDf(
prob , n , M , N [ ) ]
Calculation Result Output:
x Inv, ½ x Inv
Important!
See “Important!” under “invBinomialCDf” on page 86.
Example: To determine the minimum number of trials when

Using the Command Submenu
u Define
Function 1: Defines function and registers it with Graph Editor.
Syntax 1: Define{ y1(x) − y100(x) ; x1(y) − x100(y) ; yt1(t) − yt100(t) ; xt1(t) − xt100(t) ;
r1() − r100()} = <expression>
Example: To define the function
y = sin(x) and assign it to line “y3” of the
Graph Editor
Function 2: Creates a user-defined function.
