Hey guys, So I've got a) and b) done but I"m still not sure about c) It's asking me to find a new parametrisation of the curve for which the tangent vector is well defined at all points. And what is the value of the vector at origin? Does that just mean write it as y = x^1/3? But at the...

Oh wow, you guys are fast! I wasn't expecting a response for a few hours but you beat me to it. Thanks very much :)

I've just done a bit of reading online, and have this so far: x(t) = ti + (t^(1/3))j gives two equations x = t and y = x^1/3 with gives the equation y= x^(1/3) and then sketch from there? Is this correct or am I way off?

Ok, I just found out I have a physics assignment due tomorrow and I have no idea how to do it so I came here for help as none of the maths assistants at Uni could help me. I'm having trouble with: 1. Consider the parametric curve given by the equation x(t)= t<i> + t^(1/3)<j> - <> denotes a...
