How to find and draw the moving frame of a path?

Niels Petter Liset shared this question 10 months ago

I want to find and draw the moving frame of a path in R^3, i.e. from a curve given as x(t):=(x(t), y(t), z(t) ) find the unit tangent vector T, the unit normal vector N, N = dT/ds = dT/dt / ds/dt and the binormal vector B = T x N and draw a 3D picture of the curve with the moving frame in a point P on the curve that I can move along the curve.

Could anybody help with how I can do this?

I'm pretty new to GeoGebra, so I still find its quirks and idiosyncracies confusing and hard to navigate, so I'm thankful for all the help I can get, even simple things!

What are the functions x/y/z(t)?


Download any file, open it in GeoGebra, then open the Construction Protocol and/or Navigation Bar to see the construction steps.
