Methods & Spec students - beware of bugs.

Mini-programs for ClassPad II (or older ClassPads running OS 3.03 and later) can be downloaded and sent to your handheld using a USB cable.

Placing these mini-programs into the Library folder on your ClassPad allows access to them not only from Main and the Program application but also from within any eActivity. Watch examples of these mini-programs in the clip below.

bpn is used to find the number of trials (n) needed for
P(x ≥ a) ≥ k when *p,a,k*)
where *p* is probability of success, *a* is minimum number of successes
and *k* is required propability.

emeth applies Euler's method to find an approximate graphical
solution to a differential equation (must be explicitly defined), using the incremental formula.
In Main, type in emeth(*dy/dx,x _{0},y_{0},dx,n*), where
dy/dx is the explicit differential equation, x

fact creates a list of all the factors from *1* to *n*
of any number *n*. In Main, type in fact(*n*), where *n* is the number
you want the factors of and they are returned in a list. This list is stored as the variable
*flist* and can be retrieved at any time by typing *flist*.

pas creates a list of all the coefficients in the nth row of Pascal triangle.
In Main, type in pas(*n*), where *n* is the row you want and the
coefficients are returned in a list. This list is stored as the variable *plist*
and can be retrieved at any time by typing *plist*.

pdiv is used to divide one polynomial by another (of equal or lower order). Enter coefficients of numerator and denominator as lists (curly brackets) and the quotient and remainder are returned.

prim checks to see whether any number *n* is prime.
In Main, type in prim(*n*), where *n* is the number you want to check.

Note: OS 3.04 introduced the new **IsPrime** function,
which is similar to this function but returns TRUE or FALSE.

sci takes any number and returns it in scientific notation (standard form).
In Main type in sci(*number*).

tpt takes a quadratic expression in any form and returns it in turning point
(completed square) form. In Main type in tpt(*expression*), where *expression*
is the quadratic you want to find the turning point of.
