Calculus III
Multivariable calculus — vectors, partial derivatives, multiple integrals, and the great integral theorems.
What You'll Learn
A full semester of calculus iii — completed at your own pace, with no deadlines or fixed class times.
What You'll Be Able to Do
- Perform vector operations in 2D and 3D space — including dot product, cross product, and projections — and apply them to geometric problems involving lines, planes, and quadric surfaces
- Analyze vector-valued functions using calculus to compute derivatives, integrals, arc length, curvature, and model motion in space
- Compute and interpret partial derivatives, gradients, and directional derivatives for multivariable functions, and apply the chain rule and linear approximation
- Solve constrained and unconstrained optimization problems for multivariable functions using critical point analysis and Lagrange multipliers
- Evaluate double and triple integrals in Cartesian, polar, cylindrical, and spherical coordinates, and apply them to compute area, volume, mass, and center of mass
- Compute line integrals of scalar and vector fields, apply the Fundamental Theorem for Line Integrals, and use Green's Theorem to relate line and double integrals
- Evaluate surface integrals over parametric and explicit surfaces, compute flux integrals, and apply Stokes' Theorem and the Divergence Theorem
