find eqn of tangent plane to surface S at point P(2,1,3)
r = (2+3t, 1-t2 , 3-4t+t2)
r = (1+u2 ,2u3-1 , 2u+1)
both lie on S.
The Attempt at a Solution
i don't really know how to start. am i suppose to find eqn of S first? then use the formula
n.(r - P) with the partial differientials fx , fy etc?
but how do ifind S? with those 2 curves? thanks!
