a.)
Find the shortest distance from the point (0,1,2) to any point
on the plane x - 2y +z = 2 by finding the function to optimize,
finding its critical points and test for extreme values using the
second derivative test.
b.)
Write the point on the plane whose distance to the point (0,1,2)
is the shortest distance found in part a) above. All the work
necessary to identify this point would be in part a). You just need
to...
