JacobiAmplitude[u, m] gives the amplitude am(u \[VerticalSeparator] m) for Jacobi elliptic functions.
Mathematica provides various ways to set up conditionals, which specify that particular expressions should be evaluated only if certain conditions hold. Conditional ...
Minors
(Built-in Mathematica Symbol) Minors[m] gives the minors of a matrix m. Minors[m, k] gives the k\[Null]\[Null]^th minors.
The basic problem of the calculus of variations is to determine the function u(x) that extremizes a functional F=∫_SubscriptBox[x^StyleBox[min, FontSlant -> Italic], ...
EquationTrekker[eqn, x, {t, t_min, t_max}] opens a graphical interface for specifying initial conditions and plotting the resulting numerical solution to the first or second ...
FactorTerms[poly] pulls out any overall numerical factor in poly. FactorTerms[poly, x] pulls out any overall factor in poly that does not depend on x. FactorTerms[poly, {x_1, ...
Log10
(Built-in Mathematica Symbol) Log10[x] gives the base-10 logarithm of x.
InterpolatingPolynomial[{f_1, f_2, ...}, x] constructs an interpolating polynomial in x which reproduces the function values f_i at successive integer values 1, 2, ... of x. ...
PiecewiseExpand[expr] expands nested piecewise functions in expr to give a single piecewise function. PiecewiseExpand[expr, assum] expands piecewise functions using ...
Mathematica normally assumes that all your variables are global. This means that every time you use a name like x, Mathematica normally assumes that you are referring to the ...
