How do you find the area under the curve using Riemann sums with

f(x) = 9 - x^2, a=0 b=4

How are you supposed to set it up so that the constant doesn't become insignificant when you take the limit? Thank you.

Let's use the right endpoint method:

But,

Now, take the limit:

See what the limit is?. That's your solution.
