| options | |||
| ) |
Constructor.
- Parameters:
-
arg (Exponented, Exponented)|(RANDOMLY, <type>) (randomly) types details : - monom0_polyn1 will create this kind of objects : 5(3x-2)
- monom1_polyn1 will create this kind of objects : -5x(2-3x)
- polyn1_polyn1 will create this kind of objects : (5x+1)(3x-2)
- minus_polyn1_polyn1 will create -<polyn1_polyn1>
- sign_exp will create ±(±ax²±bx±c) | ±(±bx±c) | ±(±ax²±c) | ±(±ax²±bx)
options reversed|randomly_reversed=<nb> Options details : - reversed will change the sums' order. This is useless if the sums are the same kind of objects (like (2x+3)(3x-7))
- randomly_reversed=0.3 will change the sums' order in a ratio of 0.3
- Warning:
- Might raise an UncompatibleType exception.

| def core.base_calculus.Expandable.expand_and_reduce_ | ( | self | ) |
The expanded & reduced object, like 2×(x+3) would return 2x + 6 Take care that the resulting Sum might not be reduced itself.
For instance, (3 + x)(2x - 5) would return 6x - 15 + 2x² - 5x The rest of the calculation has to be done with the Sum's reduction method ?
