Use Lagrange multipliers to find the point on the given plane that is closest to the following point.
x − y + z = 6; (2, 7, 3)
Assuming the point to be (x,y,z) then we will find its distance,d, from the given point (2,7,3). Let us define f(x,y,z)= d2 = (x-2)2+(y-7)2+(z-3)2 and let g(x,y,z)=x-y+z-6 such that g(x,y,z)=0. Then putting amd find the value of . Then the point (x,y,z) can be found out.
