Davide Marengo,Michele Settannihings, piecewise constant functions only attain a finite number of values (as opposed to most functions in real life, which can take an infinite number of values). Once one learns how to integrate piecewise constant functions, one can then integrate other Riemann integrable functions by a similar pr

Digital Phenotyping and Mobile SensingIn the previous two chapters we have seen what it means for a sequence . of points in a metric space . to converge to a limit .; it means that . or equivalently that for every . there exists an . 0 such that . for all .. (We have also generalized the notion of convergence to topological spaces . but in this chapter we will focus on metric spaces.)

Digital Phenotyping and Mobile SensingWe now discuss an important subclass of series of functions, that of .. As in earlier chapters, we begin by introducing the notion of a formal power series, and then focus in later sections on when the series converges to a meaningful function, and what one can say about the function obtained in this manner.

https://doi.org/10.1007/978-3-030-31620-4In the previous chapter we discussed differentiation in several variable calculus. It is now only natural to consider the question of integration in several variable calculus.
