Homework Statement
I am getting rather confused when I attempt to solve one of these double integral problems.
A typical problem is phrased like this:
If R = [-1, 3][3,5], use a Riemann sum with m = 4, n = 2 to estimate the value of the following
[tex]\int\int(y^{2}-2x^{2}[/tex]
The problem will then say something like "Take the sample points to be the upper left corners of the squares." What does this mean? There seems to be four separate conditions -- upper left corners, lower left corners, upper right corners, lower right corners.
I am trying to understand what each of these conditions means and how it changes how I solve the problem (I believe it typically changes my x/y set to use).
