Question
**Task: Determine if Vector Fields are Conservative** For each of the following vector fields \( \mathbf{F} \), decide whether it is conservative or not by computing \( \text{curl} \, \mathbf{F} \). Type in a potential function \( f \) (that is, \( \nabla f = \mathbf{F} \)). If it is not conservative, type N. A. \( \mathbf{F}(x, y) = (-10x - 1y) \mathbf{i} + (-1x + 10y) \mathbf{j} \) \( f(x, y) = \) [ ] B. \( \mathbf{F}(x, y) = -5y \mathbf{i} - 4x \mathbf{j} \) \( f(x, y) = \) [ ] C. \( \mathbf{F}(x, y, z) = -5x \mathbf{i} - 4y \mathbf{j} + \mathbf{k} \) \( f(x, y, z) = \) [ ] D. \( \mathbf{F}(x, y) = (-5 \sin y) \mathbf{i} + (-2y - 5x \cos y) \mathbf{j} \) \( f(x, y) = \) [ ] E. \( \mathbf{F}(x, y, z) = -5x^2 \mathbf{i} - 1y^2 \mathbf{j} + 5z^2 \mathbf{k} \) \( f(x, y, z) = \) [ ]
