Suppose you need to know an equation of the tangent plane at a surface S at the point P(3, 1, 3). You don't have an equation for S but you know the following curves both lie on S. r1(t) = <3 + 3t, 1 - t2, 3 - 5t + t2> r2(u) = <2 + u2, 2u3 - 1, 2u + 1> Find an equation of the tangent plane at P.
Find the distance between the point (4,1,-2) and the liner(t)=<1+t, 3-2t, 4-3t>
Find a vector parametric equation r? (t) for the line through the points P=(-4,-3,5) and Q=(-2,-8,3) for each of the given conditions on the parameter t . (a) If r? (0)=<-4,-3,5> and r? (5)=<-2,-8,3> , then r? (t)= (b) If r? (3)=P and r? (7)=Q , then r? (t)= (c) If the points P and Q correspond to the parameter values t=0 and t=-2 , respectively, then r? (t)=
