I (Built-in Mathematica Symbol)

I represents the imaginary unit Sqrt[-1].

Plot (Built-in Mathematica Symbol)

Plot[f, {x, x_min, x_max}] generates a plot of f as a function of x from x_min to x_max. Plot[{f_1, f_2, ...}, {x, x_min, x_max}] plots several functions f_i.

NResidue (Numerical Calculus Package Symbol)

NResidue[expr, {z, z_0}] numerically finds the residue of expr near the point z = z_0.

NMaximize (Built-in Mathematica Symbol)

NMaximize[f, x] maximizes f numerically with respect to x.NMaximize[f, {x, y, ...}] maximizes f numerically with respect to x, y, .... NMaximize[{f, cons}, {x, y, ...}] ...

Piecewise (Built-in Mathematica Symbol)

Piecewise[{{val_1, cond_1}, {val_2, cond_2}, ...}] represents a piecewise function with values val_i in the regions defined by the conditions cond_i. Piecewise[{{val_1, ...

BindEvent (GUIKit Package Symbol)

BindEvent[name | {target, name} | {target, name, filter}, object | script | call, ...] binds an event from one object to a listener or to a script.

Cosh (Built-in Mathematica Symbol)

Cosh[z] gives the hyperbolic cosine of z.

EllipticTheta (Built-in Mathematica Symbol)
