The attached pdf shows integral approximations of two sums, which are done in my book. In the first there is no result but the book simply states that one can approximate the sum by an integral.
My question is: How is this done? Normally when you approximate a sum by an integral you have a sum of the form:
∑f(x)Δx, where Δx is small. But this is not the case here.
