Invertible Functions. Arc-length and Path-lengthLet I be an interval in ?, let f be a function I → ?, and let J = f(I). If f(x) = f(x′) ? x = x′, then f is .. If so, there is function f.: J → I such that for each x ∈ I, f. (f(x)) = x, and for each y ∈ J, f(f.(y)) = y. (To be precise, f. = {(y,x)|(x,y) ∈ f}.) f. is called the . of f.

Power SeriesA . series is a series of the form . where a. ∈ ? for each i. Evidently the convergence of a power series may depend on the value assigned to x. Evidently every such series converges for x = 0.

Cardinality. Finite and Countable SetsIn the preceding sections, we have been making informal use of the idea of a finite set. This idea is worth re-examining, and also we need to know about various types of infinite sets.
