A problem in calculus
Hi I have a problem to solve. Let x(z)= a4*z^4+a3*z^3+a2*z^2+a1*z+1 be a polynomial in z. I want the formula of the j'th derivative in z of (x(z))^(1/2). I think this kind of problems should have been solved. But I do not know where to find the formula. Could someone please find it for me? Thank you very much!
