Help for reference of the following info.
Bilinear basis function (for 4-node quadrilateral element) yields higher
convergence rate than strict linear basis function (for 3-node triangular
element).
I can't find any book provides the info of the convergence rate for comparing
the linear and bilinear basis function. Could anybody by any chance know this?
Thanks!

Are you sure about this?
Maybe I am wrong, I thought their convergence rates are same.
