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...
