Fun with Green's Theorem!

[Random Variable]

Calculating the Area of Arbitray Shapes

That's pretty cool

Green's theorem has many interesting applications...I've used it a couple of times at work.

I dont get why its so cool.... maybe becuase I despise math?

probably

It sounds familiar, I probably "learned" it back in Calc III or IV. I don't remember any of that stuff anymore.

i feel sorry for you.

the area in pixels should not be squared, a pixel is a measurement of area, not distance. The way it is now is akin to saying "I own 47 acres squared of land"

Ummm...huh?

a pixel is a rectangular portion of a screen. It is not a distance. when you calculate the area wqith that app, it gives an answer like "area = 123 pixels squared"

And that's what it should be. Area is length times width.

no, it should display "area = 12434 pixels" not "pixels squared"

example (for the purpose of this example [] will be a pixel):

[] <- 1 pixel

[][][][] <- 4 pixels, not "4 pixels squared"

a pixel is a rectangular area, not a straight line distance.

But they're saying that each pixel equals 1 unit. Which means that each square is 25 units by 25 units, or 625 units (or in this case pixels) squared.

EDIT: Just change the word "pixels" to "units" if it bothers you.
