Estimate \int _2^4\: e^x dx using the right endpoint method with n=5. Sketch a picture.

Answer 1

If n = 5 then Δx = (4 - 2)/5 = 0.4. Calculate function values at each right-side point:

f(2.4)

f(2.8)

f(3.2)

f(3.6)

f(4)

Add them up, multiply by Δx and you have your answer. The graph looks like this:
