1.
A function L has the property that L'(x) = 1/x for x≠0.
Determine the derivative with respect to x of L(X^2 + 1).
2.The number a is called a double zero (or a zero of multiplicity 2)
of the polynomial P if
P(x) = (x-a)^2 q(x) and q(a)≠0.
Prove that if a is a double zero of P,then a is a zero of both P and P',
and p"(a)≠0.
