Homework Statement
This question is about finding the smallest bowl to contain all the water being spurt out of a water spray head.
They used the lagrange multipliers to solve it which I understand, but the the envelope doesn't look like a parabola to me??
Isn't the envelope supposed to be a curve that is parallel to a certain point on every member of a family curve?
The Attempt at a Solution
I don't even see how it's possible to draw a curve that's tangential to all water-jet curves..
