23: 1.4 Calculus of One Variable

… ► $c$ and $d$ constants. … ►A generalization of the Riemann integral is the Stieltjes integral ${\int }_a^{b}f(x)d\alpha (x)$, where $\alpha (x)$ is a nondecreasing function on the closure of $(a,b)$, which may be bounded, or unbounded, and $d\alpha (x)$ is the Stieltjes measure. … ►Definite integrals over the Stieltjes measure $d\alpha (x)$ could represent a sum, an integral, or a combination of the two. Let $d\alpha (x)=w(x)dx+{\sum }_{n=1}^N{w}_n\delta \left(x-x_n\right)dx$, $x_n\in (a,b)$, $n=1,\mathrm{\dots }N$. … ►for any $c,d\in (a,b)$, and $t\in [0,1]$. …
