The capital sigma is just addition of all n amount so how do we incorporate differatiating each equation as a y value on one rectangle will be different than a y value on another?

  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Like here you get some $x_i^$, so the area of a rectangle is $(f(x_i^)-g(x_i^*))\Delta x$

Then you sum each area, and take the limit
