The convergence of the second integral is concluded by the following, which we can do

So we have shown that if x 1 6= x 2 then gx 1 6= gx 1. Thus all the elements of the form gxare distinct. Similarly, we have to show that if x 1 6= x 2 2Gthen ...

(f +g)(x) = f(x) +g(x). For instance, if f(x) = sinx and g(x) = √ 1−x, then (f +g)(x) = f(x) +g(x) = sinx+ √ 1−x. If f and g are defined on I, then their sum is as well, so this defines an addition on the set FI. If f is a function in FI and α is a real number, we define the product αf by (αf)(x) = αf(x). For instance, if f(x ...
