Teorema de Weierstrass

The Weierstrass Theorem states that any continuous function defined on a closed and bounded interval (like from point A to point B) can be approximated as closely as desired by a polynomial function. In simpler terms, it means you can find a polynomial curve that nearly matches the original function's values everywhere within that interval, no matter how precise the approximation needs to be. This theorem highlights the power of polynomials as flexible and effective tools for approximating a wide range of continuous behaviors in mathematics.
