Exponent[expr, form] gives the maximum power with which form appears in the expanded form of expr. Exponent[expr, form, h] applies h to the set of exponents with which form ...

expr[[i]] or Part[expr, i] gives the i\[Null]^th part of expr. expr[[-i]] counts from the end. expr[[i, j, ...]] or Part[expr, i, j, ...] is equivalent to expr[[i]][[j]] .... ...

Mathematica's symbolic architecture and sophisticated mathematical capabilities allow it to take a uniquely high-level approach to geometric transformations—supporting ...

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.

The differential equations that arise in practice are of two types. Here is an example of the first type. Here is an example of the second type. This equation has a symbolic ...

Unicode: 21D2. Alias: Esc ␣=> Esc. Infix arrow operator. x ⇒ y is by default interpreted as DoubleRightArrow[x,y]. Used in mathematics to indicate various strong forms of ...

Unicode: 301A. Alias: Esc [[ Esc. Compound operator with built-in evaluation rules. m〚i,j,… 〛 is by default interpreted as Part[m,i,j,…]. Sometimes used in mathematics to ...

Mathematica usually pays no attention to whether variables like x stand for real or complex numbers. Sometimes, however, you may want to make transformations which are ...

FactorList[poly] gives a list of the factors of a polynomial, together with their exponents.

PseudoInverse[m] finds the pseudoinverse of a rectangular matrix.
