Find the tangent plane to the surface of the paraboloid at the point (1,1,2). This will be of the form ax + by + cz = d
Use the normal vector of the plane from step 1, this will be the vector <a,b,c>, as the direction vector for the line.
Write your solution. The line has the form:
(1,1,2) + t<a,b,c>
where t is a parameter. Write the line in the required form (the vector form, the symmetric form, or the parametric form)
