The ptayl command finds
the Taylor expansion for a polynomial (which will be finite).
- 
ptayl takes two arguments:
- 
P, a polynomial given by a symbolic expression
or by the list of its coefficients.
- a, a number.
 
- ptayl(P,a) returns the
polynomial T such that P(x)=T(x−a).
Examples
Output, the polynomial T:
i.e. x2+2x+1=(x−2)2+6(x−2)+9.
