InverseSeries   (Built-in Mathematica Symbol)
InverseSeries[s] takes the series s, and gives a series for the inverse of the function represented by s. InverseSeries[s, x] uses the variable x in the inverse series.
LocallyExact Method for NDSolve   (Mathematica Tutorial)
A differential system can sometimes be solved by analytic means. The function DSolve implements many of the known algorithmic techniques. However, differential systems that ...
\[Equal]   (Mathematica Character Name)
Unicode: F431. Alias: Esc == Esc. Infix operator with built-in evaluation rules. x  y is by default interpreted as Equal[x,y] or x==y. \[Equal] is drawn longer than ...
Linear and Quasi-Linear PDEs   (Mathematica Tutorial)
First-order PDEs are usually classified as linear, quasi-linear, or nonlinear. The first two types are discussed in this tutorial. A first-order PDE for an unknown function ...
FindArgMax   (Built-in Mathematica Symbol)
FindArgMax[f, x] gives the position x_max of a local maximum of f.FindArgMax[f, {x, x_0}] gives the position x_max of a local maximum of f, found by a search starting from ...
ChineseRemainder   (Built-in Mathematica Symbol)
ChineseRemainder[{r_1, r_2, ...}, {m_1, m_2, ...}] gives the smallest non-negative x that satisfies all the integer congruences x mod m_i = r_i mod m_i.
FindArgMin   (Built-in Mathematica Symbol)
FindArgMin[f, x] gives the position x_min of a local minimum of f.FindArgMin[f, {x, x_0}] gives the position x_min of a local minimum of f, found by a search starting from ...
Diophantine Polynomial Systems   (Mathematica Tutorial)
A Diophantine polynomial system is an expression constructed with polynomial equations and inequalities combined using logical connectives and quantifiers where the variables ...
DiscreteLQRegulatorGains   (Built-in Mathematica Symbol)
