Question

How do you use Riemann sums to evaluate the area under the curve of f(x)=In(x) on the closed interval [3,18], with n=3 rectangles using right, left, and midpoints?

Answer 1

· I will use what I think is the usual notation throughout this solution. ∫(x)=(x) 3dx. Note that f(x)=x3 and a=3 and b=18. n=3
