Homework Statement
I need to parametrize the equations z = x^2 and x = y^2 in order to find the unit tangent vector, normal vector, and binormal vector.
Homework Equations
z = x^2 and x = y^2
The Attempt at a Solution
I tried setting x = t, so then y = [itex]\sqrt{}t[/itex] and then z = t^2.
Using that equation r(t) = < t, [itex]\sqrt{}t[/itex] , t^2> I would get completely wrong answers from the book, and if I tried another function like r(t) = < t^2 , t , t^4> , I would get different results from my previous vector. Any ideas?
