- PartialFractions( <Function> )
- Yields, if possible, the partial fraction of the given function for the main function variable. The graph of the function is plotted in the
Graphics View. - Example:
PartialFractions[x^2 / (x^2 - 2x + 1)]yields 1 + \frac{1}{(x - 1)²} + \frac{2}{x-1}.
Hint: In the 
CAS View you can also use the following syntax:
- PartialFractions( <Function>, <Variable> )
- Yields, if possible, the partial fraction of the given function for the given function variable.
- Example:
PartialFractions[a^2 / (a^2 - 2a + 1), a]yields 1 + \frac{1}{(a - 1)²} + \frac{2}{(a-1)}.
