Why is it interesting?

Vector calculus is an important tool, whenever we want to understand systems where directions play a role. A vector is an arrow that points in some direction. Thus, a vector is a tool to denote a direction.

This is needed, for example, to describe in which spatial direction a ball moves or how a fluid flows.

Important Vector Calculus Concepts:

• Curl
• Gradient
• Flux
• Divergence
• Dot Product / Scalar Product
• Cross Product
• Gauss' Divergence Theorem
• Stokes's Theorem
• coordinates
