These are a few [lifesaving] functions that I [mostly] wrote for my MAT 214 course (Multivariable Calculus I, Calculus III). Functions include: Arc Length Parametrization, Arc Length, Curvature, Discriminant, Directional Derivatives, Unbounded/Bounded Extrema, Gradient, Normal Vector, Tangent Vector, Tangental Planes, Oscillating Circles, Magnitude, Vector Projection, and Torsion.
