Epilog (Built-in Mathematica Symbol)

Epilog is an option for graphics functions that gives a list of graphics primitives to be rendered after the main part of the graphics is rendered.

Equal (Built-in Mathematica Symbol)

lhs == rhs returns True if lhs and rhs are identical.

Equivalent (Built-in Mathematica Symbol)

Equivalent[e_1, e_2, ...] represents the logical equivalence e_1 \[DoubleLeftRightArrow] e_2 \[DoubleLeftRightArrow] ..., giving True when all of the e_i are the same.

Erfc (Built-in Mathematica Symbol)

Erfc[z] gives the complementary error function erfc(z).

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).
