Sum


Recommended Posts

how do you read [math]R(f,P)[/math] I know that P is the partition and that it means the same thing as [math]\sum_{j=1}^k{f(x_j)}[/math], but what is f?

 

in [math]\sum_{j=1}^k{f(x_j)}[/math], i think j is the lower bound and k is the upper. is that the case? like j is the start and k is the end. well, that is how i use it and it works (at least for the Mercator series)
