EllipticLog[{x, y}, {a, b}] gives the generalized logarithm associated with the elliptic curve y^2 = x^3 + a x^2 + b x.
EllipticNomeQ[m] gives the nome q corresponding to the parameter m in an elliptic function.
EllipticPi[n, m] gives the complete elliptic integral of the third kind \[CapitalPi] (n \[VerticalSeparator] m). EllipticPi[n, \[Phi], m] gives the incomplete elliptic ...
EllipticTheta[a, u, q] gives the theta function \[CurlyTheta]_a (u, q) (a = 1, ..., 4).
EllipticThetaPrime[a, u, q] gives the derivative with respect to u of the theta function \[CurlyTheta]_a (u, q) (a = 1, ..., 4).
EmitSound[snd] emits the sound snd when evaluated. EmitSound[{snd_1, snd_2, ...}] emits each of the sounds snd_i in sequence.
EmpiricalDistribution[{x_1, x_2, ...}] represents an empirical distribution based on the data values x_i.EmpiricalDistribution[{{x_1, y_1, ...}, {x_2, y_2, ...}, ...}] ...
EmptyGraphQ[g] yields True if g is an empty graph and False otherwise.
Enabled
(Built-in Mathematica Symbol) Enabled is an option for objects such as Slider that specifies whether the objects should be enabled for interactive manipulation.
E
(Built-in Mathematica Symbol) E is the exponential constant E (base of natural logarithms), with numerical value \[TildeEqual] 2.71828.
