(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

suppose f(x) = x^{2}and let I = [0,2]

i) if partition I is subdivided into n subintervals of equal length, write down the length of each subinterval,[tex]\Delta[/tex]x

ii) if c_{i}, is the left endpoint of subinterval i, find c_{i}. hence find f(c_{i})[tex]\Delta[/tex]x

2. Relevant equations

N/A

3. The attempt at a solution

i) length of subintervals, T_{a}= ([tex]\frac{2a}{n^2}[/tex])^{2}, a=1,2,..,n

ii) i don't understand what the question want, left endpoint of subinterval i, what actually "subinterval i"?? owho help im not really god in english
