Sample Problems and Solutions from Nelson Chapter 5

Example 1: Calculating a Double Integral over a Region

Calculate the area enclosed by the curves y = x² and y = 4x.

Solution:

1. Find the points of intersection by setting x² = 4x:
2. x² - 4x = 0 → x(x - 4) = 0 → x = 0 or x = 4
3. Set up the double integral for the area:

\[ A = \int_{x=0}^{4} \int_{y=x^2}^{4x} dy \, dx \]

4. Integrate with respect to y:

\[ A = \int_{0}^{4} (4x - x^2) dx \]

5. Compute the integral:

\[ A = \left[ 2x^2 - \frac{x^3}{3} \right]_0^4 = \left( 2 \times 16 - \frac{64}{3} \right) - 0 = 32 - \frac{64}{3} = \frac{96 - 64}{3} = \frac{32}{3} \]

Answer: The area enclosed by the curves is \(\frac{32}{3}\) square units.

Example 2: Vector Field Divergence

Calculate the divergence of the vector field \(\mathbf{F}(x, y, z) = x^2 \mathbf{i} + y^2 \mathbf{j} + z^2 \mathbf{k}\).

Solution:

1. Recall the divergence formula:

\[ \nabla \cdot \mathbf{F} = \frac{\partial P}{\partial x} + \frac{\partial Q}{\partial y} + \frac{\partial R}{\partial z} \] where \(\mathbf{F} = P \mathbf{i} + Q \mathbf{j} + R \mathbf{k}\).

2. Calculate each partial derivative:

\[ \frac{\partial P}{\partial x} = \frac{\partial x^2}{\partial x} = 2x \] \[ \frac{\partial Q}{\partial y} = \frac{\partial y^2}{\partial y} = 2y \] \[ \frac{\partial R}{\partial z} = \frac{\partial z^2}{\partial z} = 2z \]

5. Sum the derivatives:

\[ \nabla \cdot \mathbf{F} = 2x + 2y + 2z \]

Answer: The divergence of \(\mathbf{F}\) is \(2x + 2y + 2z\).

Example: Suppose r(t) = (2t, t², sin t). - Interpretation: The position of a particle moving in 3D space at time t. - Graphical Representation: Plotting x(t), y(t), and z(t) over a domain. Derivatives of Vector Functions The derivative r'(t) provides the velocity vector: - r'(t) = dx/dt i + dy/dt j + dz/dt k. Physical Meaning: - The velocity vector indicates the direction and speed of the particle's movement at time t. - The magnitude |r'(t)| gives the speed. Calculating Derivatives: - For r(t) = (x(t), y(t), z(t)), differentiate each component separately. - Example: - Given r(t) = (3t², 4t, cos t), - r'(t) = (6t, 4, -sin t).

Parameterize the curve as r(t) over [a, b]. 2. Find r'(t). 3. Substitute into the integral. Physical Interpretation: - Represents the work done by a force field in moving an object along C. Curvature and Torsion - Curvature (κ) measures how sharply a curve bends at a point. - Torsion (τ) measures how much the curve twists out of the plane of curvature. - Formulas involve derivatives of r(t): - κ = |r'(t) × r''(t)| / |r'(t)|³. - τ = ((r'(t) × r''(t)) · r'''(t)) / |r'(t) × r''(t)|².
