Scale[g, s] represents graphics primitives g scaled by a factor s. Scale[g, s, {x, y, ...}] scales with the point {x, y, ...} kept fixed. Scale[g, {s_x, s_y, ...}, ...] ...

SelectionMove[obj, dir, unit] moves the current selection in an open notebook in the front end in the direction dir by the specified unit. SelectionMove[obj, dir, unit, n] ...

Thickness[r] is a graphics directive which specifies that lines which follow are to be drawn with thickness r. The thickness r is given as a fraction of the horizontal plot ...

Throw[value] stops evaluation and returns value as the value of the nearest enclosing Catch. Throw[value, tag] is caught only by Catch[expr, form] where form is a pattern ...

UnitVector[k] gives the two-dimensional unit vector in the k\[Null]^th direction.UnitVector[n, k] gives the n-dimensional unit vector in the k\[Null]^th direction.

Xor[e_1, e_2, ...] is the logical XOR (exclusive OR) function. It gives True if an odd number of the e_i are True, and the rest are False. It gives False if an even number of ...

Mathematica uses the Microsoft math recognizer that is built into Windows 7 to recognize handwritten mathematical expressions. This allows you to enter handwritten ...

Different kinds of vector and matrix multiplication. This multiplies each element of the vector by the scalar k. The "dot" operator gives the scalar product of two vectors.

The Mathematica function NIntegrate is a general numerical integrator. It can handle a wide range of one-dimensional and multidimensional integrals. Finding a numerical ...

Mathematica notebooks allow you to create documents that can be viewed interactively on screen or printed on paper. Particularly in larger notebooks, it is common to have ...
