Mean curvature of a surface (just stuck with some simplifying!)
Hi everyone, new here and trying to calculate the mean curvature for the following surface:
I have been through the process of finding tangent vectors and a unit normal vector to the surface, so up to the point where I have had to substitute 6 scalars into:
The only problem I seem to be having is not being able to simplify it... This is what I have:
Maybe missing something really simple here or I have made a mistake in calculating the scalars.
Any help, much appreciated!
(I have reposted this in University Maths - geometry, as it's in the wrong place.. any hints on how to delete this one though?)
