Question
### Problem Statement 3. Consider the curve \(\mathbf{r}(t) = \mathbf{i} + \left(\sqrt{2} \ln(t)\right)\mathbf{j} + \frac{1}{t}\mathbf{k}\). b) Find the curvature at the point where \(t = 1\). Hint: Use the most appropriate equation for \(\kappa(t)\). ### Explanation The problem involves analyzing a vector-valued function representing a curve in three-dimensional space. The components of the curve \(\mathbf{r}(t)\) are given as: - \(\mathbf{i}\) component: constant value of 1. - \(\mathbf{j}\) component: \(\sqrt{2} \ln(t)\). - \(\mathbf{k}\) component: \(\frac{1}{t}\). The task is to determine the curvature \(\kappa(t)\) at the specific point where \(t = 1\). Curvature measures how sharply a curve bends at a given point and is crucial to understanding the geometry of the curve in space. The hint suggests using an appropriate formula for \(\kappa(t)\), which typically involves derivatives of the curve's components.
