Consider a curve lying on the cylinder x^2 + y^2 = 1 and given by the vector function r(t) = (cost,sin t, t^2), for t ≥ 0.

Find equations of normal planes at the points (1, 0, 0) and (1, 0, 4π^2)

Hi, I don't really know how to start this. I know the formula for a plane. a(x-xo)+b(y-yo)+c(z-zo)=0 I guess I need help finding the normal vectors
