Maybe I just need to think about what that means. <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/134.137.180.129|134.137.180.129]] ([[User talk:134.137.180.129#top|talk]]) 19:15, 13 July 2018 (UTC)</small> <!--Autosigned by SineBot-->

the article is one of the best introduction.But in weak formulation of p2 the grrens identity is not clear. we are ina plane region. explicit derivation be done.
in p1 use of mean value theorem be dmade explicit. Also the approach of distribution via sequential convergence and distributional derivative can be indicated in few lines.
on the contary tooo much space is used for h and the denedence on h. tthe whole can be summarized in h as the diameter of the traingle maximum amongst all traingles thas all very simple notion.
Further use of space H H be made clear. why not take H as space of continuous and differentiable except at finitely many points and make matters simple.
use of riesz representation be explicit write the functional and how to express it as inner product with u by RRT. excellent ouline which can be rigorous proof if we restrict H to be a suitable space.
please avoid lengthy discussions on h and subdivisions can be understood intuitively. But solve an explict one dime problem completely .
Also use of Gallerkin is not made explicit . please make that use explicit in the problem.
if these changes are done this can be most seductive logical introduction to fem . no good succint explnation exists on NET
