In this video, I give a quick nuts and bolts way on how to use Riemann sums (left endpoints, right endpoints and midpoint) as well as 2 trapezoidal examples using a data table. The first example has uneven intervals (for which I can't do the midpoint method-Why??) and then the second example uses even intervals where I can use the midpoint method (and use the trapezoidal formula). Both examples are with data and not an equation. However, if you can make a data table from your equations, you can use the same method! Notes sheets are posted at the bottom for the problems I went through.
