Express the limit as a definite integral on the given interval.
n xi ln(1 + xi2) Δx, [0, 4] http://www.webassign.net/wastatic/wa...ex/img/sum.gif i = 1
My work: I figured out that f(x) = xln(1+x^2)
therefore we need to find the integral from 0 to 4 of xln(1+x^2)dx
I'm a little confused. Do I start by making a graph? I haven't memorized the log graphs so sorry for my naivety. I appreciate any help.
