In this video, we look at computing a Riemman sum for n subintervals and then find the area under the curve by computing the limit as n goes to infinity.

hello there! can you please help with this particular one? I tried solving it myself but always end up with 40/3 as my answer. however 64/3 is said to be the correct answer.
PROBLEM: 2Xsquare + X a = 1, b = 3 at n subinterval
I'm used to the value of a being a = 0
I'm really looking forward to you solving this problem.

Would the final answer be "(16/3)units^2"

How come no tutor made video for polynomial function for Riemann Sum that is higher than x^3 power, such as x^4, x^5, x^6, and so on? Those definition we can apply such as Riemann Sum formulas for i, i^2, and i^3 get whacked out... We can't apply i^2 * i^3 for i^5. Did anyone notice it?
