Hi Everyone,
I'm currently studying for my maths exam and I'm stuck on one of the questions. I need to Find the Tangent and Normal vectors and then the curvature. The equation for the curve is:
r(t) = (t, 1/2t2, t2)
my working is attached, if anyone can help me out and show me where I went wrong I'd appreciate it.
EDIT
I just realised, should |r'(t)| = 1+sqrt(5)t instead of 1+3t?
