WeierstrassPPrime[u, {g_2, g_3}] gives the derivative of the Weierstrass elliptic function \[WeierstrassP](u; g_2, g_3).
InputForm[expr] prints as a version of expr suitable for input to Mathematica.
StandardForm[expr] prints as the standard Mathematica two-dimensional representation of expr.
Defer
(Built-in Mathematica Symbol) Defer[expr] yields an object that displays as the unevaluated form of expr, but that is evaluated if it is explicitly given as Mathematica input.
AppellF1[a, b_1, b_2, c, x, y] is the Appell hypergeometric function of two variables F_1 (a; b_1, b_2; c; x, y).
