The FROOTS function
The function FROOTS, in the ARITHMETIC/POLYNOMIAL menu, obtains the roots and poles of a fraction. As an example, applying function FROOTS to
the result produced above, will result in: [1
Another example is:
21.], i.e., poles = 0 (2), 1(1), and roots = 3(1), 2(1). If you have had Complex mode selected, then the results would be:
[0
Step-by-step operations with polynomials and fractions
By setting the CAS modes to Step/step the calculator will show simplifications of fractions or operations with polynomials in a
