EdgeShapeFunction is an option and property for Graph and related functions that specifies a function to use to generate primitives for rendering each edge.
Editable is an option for displayed objects, cells, and notebooks that specifies whether their contents can be edited interactively using the front end.
EditCellTagsSettings -> {opt_1 -> val_1, opt_2 -> val_2} is a global option that specifies settings for the Edit Cell Tags dialog box.
EigenvectorCentrality[g] gives a list of eigenvector centralities for the vertices in the graph g.EigenvectorCentrality[g, "In"] gives a list of in-centralities for a ...
EllipticExpPrime[u, {a, b}] gives the derivative of EllipticExp[u, {a, b}] with respect to u.
EllipticThetaPrime[a, u, q] gives the derivative with respect to u of the theta function \[CurlyTheta]_a (u, q) (a = 1, ..., 4).
Erf
(Built-in Mathematica Symbol) Erf[z] gives the error function erf(z). Erf[z_0, z_1] gives the generalized error function erf(z_1) - erf(z_0).
EstimatorGains[ss, {p_1, p_2, ..., p_n}] gives the estimator gain matrix for the StateSpaceModel object ss, such that the poles of the estimator are p_i.
Evaluatable is an option for Cell that specifies whether a cell should be used as input to be evaluated by the Mathematica kernel.
EvaluatePacket[expr] is a MathLink packet requesting evaluation of expr.
