LinearProgramming[c, m, b] finds a vector x that minimizes the quantity c.x subject to the constraints m.x >= b and x >= 0. LinearProgramming[c, m, {{b_1, s_1}, {b_2, s_2}, ...
ProductLog[z] gives the principal solution for w in z == w e^w. ProductLog[k, z] gives the k\[Null]^th solution.
The mathematical operations we have discussed so far are exact. Given precise input, their results are exact formulas. In many situations, however, you do not need an exact ...
MoebiusMu[n] gives the Möbius function \[Mu](n).
Apart
(Built-in Mathematica Symbol) Apart[expr] rewrites a rational expression as a sum of terms with minimal denominators. Apart[expr, var] treats all variables other than var as constants.
PolynomialRemainder[p, q, x] gives the remainder from dividing p by q, treated as polynomials in x.
TrigExpand[expr] expands out trigonometric functions in expr.
TrigFactor[expr] factors trigonometric functions in expr.
Mathematica provides a complete data manipulation language with vast flexibility in rearranging lists with any number of elements in any kind of structure.
IntegerLength[n] gives the number of digits in the base 10 representation of the integer n.IntegerLength[n, b] gives the number of digits in the base b representation of n.
