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)

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:

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:
