Part 1: Gradient and Directional Derivative [5 marks]
Definition of Gradient: The gradient of a scalar function $f(x,y,z)$ is defined as: $$
Part 1: - Function: $f(x,y,z) = x^3 - xy^2 + z$ - Point: $P(1,0,0)$ - Direction: $\vec{v} = 2\vec{i} - \vec{j} + \vec{k}$ Part 2: - Region bounded by $y = \sqrt{x}$, line $y = 1$, and $x = 4$ - Axis of revolution: $y = 1$ All data present and readable. --- Definition of Gradient The gradient of a...
