A normal plane

[FizzyCrow]

Thanks for any help!!!

Find the normal plane of the cure r=ti+tj+(2/3)t^(3/2) at the point (1,1, 2/3) (the plane of bandn

I am really at a loss at how to do this one!!

hmm I just recently learned how to find the tangent plane to a curve using partial derivatives, is this relevant?
