Mind-Warm-Ups Vector Spaces

Ultimate Space = S
si = arbitrary partition of S
Δsi = infinitesimal si, that is limit of si as it tends to zero.
pi = arbitrary point in S = Δsi

Problem 41: what is a normed linear space?
Ans: let X be a linear space over the field F where F is either the real field R or the complex field C.
A norm on X is a real-valued function whose value at x is denoted by ||x||, satisfying the following conditions for all x, y, in X and &lpha; in F:
(i)||x|| > 0 if x ≠ 0
(ii)||αx|| = |α|||x||
(iii)||x + y|| ≤ ||x|| + ||y||
A linear space X with a norm defined on it is called a normed linear space.
