# NX - Computer Definition

(**N**ever e**X**ecute) See never execute bit.

- (b) If
**nx**>o, (1+x). - Thus we arrive at the differential coefficient of f(x) as the limit of the ratio of f (x+8) - f (x) to 0 when 0 is made indefinitely small; and this gives an interpretation of
**nx**n-1 as the derived function of xn (ï¿½ 45)ï¿½ This conception of a limit enables us to deal with algebraical expressions which assume such forms as -° o for particular values of the variable (ï¿½ 39 (iii.)). - }
**Nx**..., it is clear that, if x,. - Observing that any factor 1/I-x l is=l+x l +x 2l +..., we see that in the term
**Nx**the coefficient is equal to the number of partitions of n, with the parts I, 2,, ..,withh repetitions. - +
**Nxnzk**+.., we see that in the term**Nx**n z k of the development the coefficient N is equal to the number of partitions of n into k parts, with the parts I, 2, 3, 4,, without repetitions.
