Thread: What do I do with this integral problem

1. What do I do with this integral problem

Consider the following table:
x 0 3 6 9 12 15
f(x) 41 40 38 34 26 9
Use this to estimate the integral:
Sigma notation[15 over 0]fxdx=

Nevermind guys, i figured it out.

Good. $\int_0^{15} f(x)dx$ can be approximated by the Riemann sum (41+ 40+ 38+ 34+ 26+ 9)(15/5)= (41+ 40+ 38+ 34+ 26+ 9)(3).
