Regular sums are discrete. Integration is continuous. · 1 year, 10 months ago

As far as I know...You can't...In reality, Integration is defined as summation over infinite values. For example, if I want you to find the number of students in a class, you will count them and tell me the result.

On the other hand, if I tell you to count number of stars in the sky, then, you would estimate the number of stars in a small area, and integrate all these small areas, which will finally give you the approximate of total number of stars. Hope this helped! · 1 year, 10 months ago

but integration can also be done within a limit. as known as definite integration, similarly for summation. does that make any difference?? · 1 year, 10 months ago

Yes, see definite integration means that you have fixed an upper and alower limit. But, still there are infinite values in those 2 values. For example, even if you set the values as 1 and 2, but there are infinite numbers betwen these 2 digits. · 1 year, 9 months ago
