Increasing-power CAS mode
When the _Incr pow CAS option is selected, polynomials will be listed so that
the terms will have increasing powers of the independent variable. If the _Incr
pow CAS option is not selected (default value) then polynomials will be listed
so that the terms will have decreasing powers of the independent variable.
An example is shown next in Algebraic mode:
In the first case, the polynomial (X+3)
5
is expanded in increasing order of the
powers of X, while in the second case, the polynomial shows decreasing
order of the powers of X. The keystrokes in both cases are the following:
„Üx+3™Q5`
In the first case the _Incr pow option was selected, while in the second it was
not selected. The same example, in RPN notation, is shown below:
The same keystroke sequence was used to produce each of these results:
³„Üx+3™Q5`µ
