Plotting a vector path on a torus

I am looking to visually represent some properties of vectors when plotted on the plane versus when the are plotted on the torus. Plotting them on the plan is relatively straight forward, however I ...

Calculating curvature of a contour

I have an equation of a scalar field in the form $$f(x, y) = x^2 + y^2 + xy + c$$ I want to find the curvature of the contour of the curve at $f_c = f(0.5, 0.5)$. So I need to calculate the ...

How can I animate the plot of this curve also showing its tangent/normal vectors at each point?

I want to animate the curve given by $\alpha(t) = (u(t), v(t))$ being traced out (and also showing the tangent and normal vector at each point), where $u$ and $v$ are the solutions below ...

Passing a function into another function defined with Module and using it there

I'm trying to write a generic module that will take a vector-valued function of a space curve and show the animation of a unit tangent vector traversing the curve. I found a really nice example from ...
