If I have a function c(x,Δx) that gives the area between x and x + Δx of a function.(adsbygoogle = window.adsbygoogle || []).push({});

The area under the function can be given by:

Sum from j = 0 to n-1 of c(b/n j,c/b)

As n tends to infinity and b is the upper limit of integration.

How can I convert this from a sum into a integral? I'm not sure if this is already in the form of a Riemann integral or not.

Thankyou in advance
