Homework Statement
Line perpendicular to a plane
Plane: z(x,y)= 0.882531*x-0.346494*y+0.383108
P1(0.5;0.1;Z)
P2(0.4;0.15;Z)
Homework Equations
The Attempt at a Solution
z(0.5,0.1) = 0.7897
z(0.4,0.15) = 0.68414
vector n=ai+bj+ck
vector P2P1 = (0.5-0.4)i + (0.1-0.15)j +(0.7897-0.68414)k
n*(P2P1) = 0.1a - 0.005b + 0.10556c
c= -0.947329(a-0.5*b)
parametric
x(t,u) = t+0.5
y(t,u)=t+0.1
z(t,u)=-0.947329(t-0.5*t)
when I put this on the graph, its not perpendicular at all... :( help
