What is true of it
E11 is E, G♯, B, D, F♯ and A — 1, 3, 5, b7, 9 and 11 counted from E.
On an instrument that cannot reach all 6, the 3, 5 and 1 go first, in that order.
The easiest of the 5 fingerings below is 000102: 2 fingers, held at the 1st fret.
3 of them use open strings, which is what makes a shape quiet to change to.
Where its notes are on the neck
The brass dots are E, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
