Course description

Most interesting things occur in systems with more than one variable: weather depends on time of year and location on the Earth, economies have several sectors, important chemical reactions have many reactants and products.

This course unpacks the unique characteristics of functions that have more than one variable and the tools needed to think about them.

Topics covered

  • 三维坐标
  • Contour Maps
  • Cross Product
  • Determinants
  • Dot Product
  • Level Sets
  • Vectors and Matrices

Prerequisites and next steps

You’ll need an understanding of algebra and the basics of functions, such as domain and range, graphs, and intercepts. You should also be familiar with exponential functions, logarithms, and basic trigonometric identities.
