Edfinity is a full-featured homework system. Use this problem series as-is, or mix-and-match with other series or your own problems as desired. Edfinity gives you complete control over the every aspect of students' online assessment experience.

## Audience

Intended for students who have passed a Integral Calculus course.

## Powered by WeBWorK

This problem series includes WeBWorK-enhanced problems. WeBWorK problems are highly sophisticated, supporting the representation and manipulation of mathematical objects such as vectors, points, matrices, intervals, and complex numbers, with customizable answer checkers. Students are encouraged to make multiple attempts until they succeed, and given immediate feedback on correctness.

Edfinity provides full access to the WeBWorK Open Public Library (OPL), a collection of over 20,000 rich, interactive problems across a wide range of math and science subjects, including college algebra, discrete mathematics, probability and statistics, single and multivariable calculus, differential equations, linear algebra and complex analysis.

## Problem Sets

- Multi-variable Functions
- Graphs of Functions \(f\colon{\bf R}^2\to{\bf R}\)
- Level Sets of Functions \(f\colon{\bf R}^2\to{\bf R}\)
- Level Surfaces of Functions \(f\colon{\bf R}^3\to{\bf R}\)
- Vectors and Vector Algebra
- Dot Products, Cross Products, Vector Projections, and Parametric Lines
- Planes in 3D and Partial Derivatives
- Directional Derivatives, Gradient Vectors, and Critical Points
- Gradient Vectors in \({\bf R}^3\), Critical Points, and Vector-valued Derivatives
- Linear Systems
- Systems of Linear Equations (optional)
