the expression 1/50 (1/50 +2/50+ 3/50+ .....50/50)is a Reimann sum approximation for

(everything in the parantheses is square root except the 1/50 outside the paratheses)

the answer has to me the integral form so from looking at the formula in my book i got:

1/50 * integral(from 0 to 50) square root x dx

hopefully i wrote the expression right in words correctly. tell me if it is confusing and i write it in different words .

My only concern with this answer is why is it from 0 to 50 isnt 50/50 1 not 50. That is my only discrepancy with your solution. so woulnt it be form 0 to 1? Im just asking

1 answer

for clarification.

Yes, you are correct. The expression should be 1/50 * integral(from 0 to 1) square root x dx.
