Finding the Coefficients of a Polynomial

To return the polynomial coefficients with respect to a particular variable, select the polynomial variable, and either:

• Type [Ctrl][Shift][.] and the "coeff" keyword followed by a comma and the polynomial variable, or use the Symbolic toolbar to modify the live symbolics operator.

  - or -

• Choose Polynomial > Find Coefficients from the Symbolics menu.

A vector containing the coefficients of the equivalent polynomial appears. If all the exponents are positive, the first element of the vector corresponds to the constant term. If all exponents are negative, the last element corresponds to the constant term. Otherwise, the coefficients are returned for the smallest exponent to the largest, in order, with zeros for any skipped exponents in the expression, always including the constant term.
