Hi. My professor assigned the attached problem.
Could anyone be of help explaining how to solve this? He hasn't explained it yet and I'm having some trouble.
Thanks very much.
Your $\displaystyle \Delta x=\frac{2-1}{5}=0.2$.
Your partition points are $\displaystyle x_k=1+k\cdot \Delta x$.
The lower sum is $\displaystyle \sum\limits_{k = 0}^4 {f(x_k )\Delta x} $
The upper sum is $\displaystyle \sum\limits_{k = 1}^5 {f(x_k )\Delta x} $.
Now just do the caluclutions.
