## What do you learn in Multivariable Calculus

Multivariable Calculus takes the concepts from single-variable calculus and extends them to functions of multiple variables. You'll learn about partial derivatives, multiple integrals, vector fields, and gradient vectors. The course covers techniques for optimizing functions of several variables and introduces line integrals, surface integrals, and the theorems of Green, Stokes, and Gauss.

## Is Multivariable Calculus hard?

Multivariable Calculus is often considered challenging, but it's not impossible. The concepts build on what you learned in earlier calculus courses, so if you did well in those, you've got a good foundation. The tricky part is visualizing things in three dimensions and juggling multiple variables at once. It takes practice, but once it clicks, it's pretty cool.
