Why are all polynomials C^infinity? I mean, if we consider the polynomial f(x)=x^2...how does that satisfy the definition. ps. badreferences u are correct

That means it's infinite dimensional complex. Are you in a modern algebra class?

\(C\) or \(\mathbb C\)?

extremity Group TitleBest ResponseYou've already chosen the best response.0
single C. I see. Now, wolfram says that all polynomials are C^infty. Can someone explain to be how f(x) = ax^2 +bx+c is C^infty? considering that it is a polynomial?

Ah okay. \(C(R)\) means the complex conjugate of \(R\). This is the sansserif \(C\) as opposed to the shell \(\mathbb C\).

At least, in particle physics. Maybe it has another meaning in higher linear algebra. Apologies. Infinity complex conjugates doesn't sound right.

All good guys ! http://sci4um.com/about19318.html So f(x)=0 is C^infinity :) im happy now ! thanks guys !

Manifold calculus? Hard stuff to learn in linear algebra.

I think it's what @helder_edwin said. Any polynomial can be differentiated to 0 by taking n+1 derivatives where n is the order of the polynomial. The derivative of 0 is 0, which can, of course, be differentiated ad infinitum. Hence all (at least finitedegree, I don't know about otherwise) polynomials are infinitely differentiable.

Yes, @extremity found it. Why do they use the same symbol as the one you use when you learn about symmetry in physics?
