3D Curves and their Tangents | Intro to Vector-Valued Functions

A space curve, or vector-valued function, is a function with a single input t and multiple outputs x(t), y(t), z(t). In this video we introduce these functions and see how to visualize them in 3D. We then turn to the problem of tangent lines to these types of curves. The definition is modeled after tangents to graphs of functions.
