Verbatim[expr] represents expr in pattern matching, requiring that expr be matched exactly as it appears, with no substitutions for blanks or other transformations.
$PrePrint is a global variable whose value, if set, is applied to every expression before it is printed.
Solving equations involving power series. Here is a power series. This gives an equation involving the power series.
MatrixExp[m] gives the matrix exponential of m. MatrixExp[m, v] gives the matrix exponential of m applied to the vector v.
ReplacePart[expr, i -> new] yields an expression in which the i\[Null]\[Null]^th part of expr is replaced by new. ReplacePart[expr, {i_1 -> new_1, i_2 -> new_2, ...}] ...
FlipView[{expr_1, expr_2}] represents an object which flips between displaying expr_1 and expr_2 each time it is clicked.FlipView[{expr_1, expr_2, ...}] cyclically flips ...
GraphDistance[g, s, t] gives the distance from source vertex s to target vertex t in the graph g.GraphDistance[g, s] gives the distance from s to all vertices of the graph g.
HararyGraph[k, n] generates the minimal k-connected graph on n vertices H k, n.
InverseFourierTransform[expr, \[Omega], t] gives the symbolic inverse Fourier transform of expr. InverseFourierTransform[expr, {\[Omega]_1, \[Omega]_2, \ ...}, {t_1, t_2, ...
