Homework Statement
find the points on the surface x^2-z^2 = 1 which are in minimum distance from (0,0)
i should find the points using d = x^2+y^2+z^2
first of all
gradf = λ gradg
where f = d and g = x^2-z^2
so we have (2x,2y,2z) = λ (2x,0,2z)
now
2x = λ2x
2y = 0 => y = 0
2z = λ2z
so λ=1
but now how can i find x and z?
im totally confused
