AddPoly (p1,p2)

Add two polynomials (vectors).

DividePoly (p,q,&r)

Divide two polynomials (as vectors) using long division. Returns the quotient of the two polynomials. The optional argument r is used to return the remainder. The remainder will have lower degree than q.

See Planetmath for more information.

IsPoly (p)

Check if a vector is usable as a polynomial.

MultiplyPoly (p1,p2)

Multiply two polynomials (as vectors).

NewtonsMethodPoly (poly,guess,epsilon,maxn)

Find a root of a polynomial using Newton's method. poly is the polynomial as a vector and guess is the initial guess. The function returns after two successive values are within epsilon of each other, or after maxn tries, in which case the function returns null indicating failure.
