Find the curvature of the space curve.
r(t) = -4i + (4+ 2t)j + (t^2 +2)k
* I was just wondering if my solution looks good so far????
r ' (t)= 0i +2j + 2tk
ll r ' (t)ll = sqrt(4 +4t^2) = 2 + 2t^2
= T(t) = r ' (t) / ll r ' (t) ll = 2j + 2tk / 2j + 2t^2K
* After this I use the quationat rule??? 99% sure???
