Calculus of Variations.

    Could anybody recommend any texts on Calculus of Variations?

    Unlike most areas of mathematics I'm finding it difficult to obtain standard texts.

    An easy book on the subject is Weinstock's "Calculus of Variations with Applications to Physics and Engineering".

    Thanks. I hit a wall when reading Nakahara's Geometry, Topology and Physics. In chapter 10 he takes the variation of the action of a scalar field and the Einstein-Hilbert action, equates them both to zero and ends up with the Field Equations.

    My basic problem is I don't know how to take a variation with respect to a tensor, such as the metric.
