Okay, here's what I have thus far, and I'm not sure this is correct: mi= 5(i-1)/n After much sigma notation and algebra... eventually ending up with 125/n3 {(n(n+1)(2n+1)/6) - 2[n(n+1)/2] + n}

Homework Statement FIND THE LOWER SUM FOR THE REGION BOUNDED BY f(x) = 25 - x^2 AND THE X - AXIS BETWEEN x = 0 and x = 5. SOLVE ANALYTICALLY! Homework Equations None that I'm aware of... The Attempt at a Solution f(x) = -x2 + 25 and \DeltaX = b-a/n = 5-0/n = 5/n Here's...
