1. The problem is to find the Wendepunkt (inflection point) of a function, which is where the curvature changes sign. 2. To find the Wendepunkt, we need to find where the second derivative of the function equals zero and changes sign. 3. The general steps are: - Find the first derivative $f'(x)$. - Find the second derivative $f''(x)$. - Solve $f''(x) = 0$ for $x$. - Check the sign change of $f''(x)$ around these points to confirm inflection points. 4. Without a specific function given, this is the general method to find Wendepunkte.
