Question :- Find the torsion of
![C : r(t) = [t, t^2, t^3]](http://www.mathhelpforum.com/math-help/latex2/img/0d53f0d77a8e5e8424499a7e70e7d03f-1.gif "C : r(t) = [t, t^2, t^3]")
Strategy :- First convert into
. Then find
(unit tangent vector). Then find the
(unit binormal vector). Then take its derivative and game is up.
Problems :- But....a biiiig BUT....I am stuck
....Till now I have done problems in which there were equations of circles and elipses etc and it was easier to convert them into parametric form and then conert into
...here I am atuck with these
s....
Questions :- 1. How do I write the parametric forms and convert them from
to
?
2. How do I find the unit normal vector vector with which I have to cross the unit tangent vector ?
Please take your time answering cuz I am stuck really bad....Thanks a lot...
Torsion - Vector Calculus - urgent kinda
