(Built-in Mathematica Symbol) Re[z] gives the real part of the complex number z.
StepMonitor is an option for iterative numerical computation functions that gives an expression to evaluate whenever a step is taken by the numerical method used.
To begin, consider an initial value problem for a linear first-order ODE. This is a linear first-order ODE. Notice that the general solution is a linear function of the ...
The equations of motion for a free rigid body whose center of mass is at the origin are given by the following Euler equations (see [MR99]). Two quadratic first integrals of ...
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.
ArcCos
(Built-in Mathematica Symbol) ArcCos[z] gives the arc cosine cos -1 (z) of the complex number z.
ArcSin
(Built-in Mathematica Symbol) ArcSin[z] gives the arc sine sin -1 (z) of the complex number z.
D
(Built-in Mathematica Symbol) D[f, x] gives the partial derivative \[PartialD]f/\[PartialD]x. D[f, {x, n}] gives the multiple derivative \[PartialD]^n f/\[PartialD]x^n. D[f, x, y, ...] differentiates f ...
