RT Journal Article SR Electronic A1 FAJKUS, Martin T1 CURVATURE, TORSION AND THE FRENET FRAME IN THE MATHEMATICA ENVIRONMENT JF Trends in education YR 2013 VO 6 IS 1 SP 60 OP 63 UL https://tvv-journal.upol.cz/en/artkey/tvv-201301-0013.php AB The article is dedicated to a program, which displays a user-defined 3D curve and calculates the curvature and the torsion at a chosen point of this curve. The user may let display tangent vector, normal vector and binormal vector at any point of the curve and also, for a good illustration, a small airplane flying along the curve as the user continuously changes its position by changing the value of the parameter of the curve.
