Find Unit Vector perpendicular to the Surface,
x3+zx=1 at the point P=(1,2,-1)
I figures that the perpendicular vector would be,
N(X)=grad(x3+zx)
= (3x2+z, 0, x)
N(P)= (3,0,1)
Then the unit vector would be,
n=N(P)/||N(P)||
n=(3/51/2,0,1/51/2)
The answer i get is not the right answer and i don't see where I am going wrong.
Thanks,
