Big O notation the input number "x" itself, because "n" = "O"(log "x"). This implies formula_18, which means that formula_19 is a convex cone. Big "O" (and little o, and Ω...) can also be used with multiple variables. To define Big "O" formally for multiple variables, suppose formula_22 and formula_23 are two functions defined on some subset of formula_24. We say if and only if Equivalently, the condition that formula_27 for some formula_28 can be replaced with the condition that formula_29, where formula_30 denotes the Chebyshev norm. For example, the statement asserts that there exist constants "C" and "M" such that where "g"("n","m")
