Hm, let's use a graphing software to save time... Aha! It seems that the equation works when d is slightly less than 15.95... thanks! :)

The problem is, there's only one possible answer for d. How would I even know if I got close? I mean, I know it's less than 24 and proooobably more than 12, but... that's just from thinking about the circles on a graph.

Numerically. Or at all. I don't know what to do when there's all this arccos and square root stuff everywhere aand I can't find out how to isolate d.

Okay, so I've found out about how circle-circle intersection works ( http://mathworld.wolfram.com/Circle-CircleIntersection.html ). I'm working with the following knowledge: The area of the overlap is 100 The two circles have the same radius, 12 d is unknown How would I solve for d in the...

... wait. *does some simple math* Never mind, I'm an idiot. Now that I think of it, I've been OVER-thinking it. There's no way to tell what the area of the other circle is. My bad. :/

It doesn't matter what I call the circles. Jimmy, James, and Jack. A, B, C. 1, 2, 3. The only thing that matters is that two are unit circles, one is larger than a unit circle, and how the three overlap. When did I contradict this? I specifically defined the two circles as unit circles...

E was given as being equal to F. E is where C and A overlap. F is where B and A overlap. Imagine it like three populations. Broguys overlap with Dudemen so that the percent of Dudemen that are Broguys is equal to the percent of Broguys that are Dudemen. This is D, 21% of the two unit circles...

Oh god. Running numbers again from the start, I realize I didn't even need help. Just a break. I ran numbers that weren't even... ugh. Running the numbers again and arriving at T, the solution became mind-numbingly simple: T = 0.105 = 0.5x = 0.5y 2T = x = y = 0.21 ! C = 0.5/U = 0.5/I...

Yeah, that's part of it. I'm trying to find X and Y, and find out the second component of both X and Y. As in, if the components of Z are 50% and 45%, that would make 0.45 ≤ Z ≤ 0.5 (but I have no idea how to do this if a component is a range) The first component of X is 20-25%, and the first...

(This isn't homework, so I guess it'd go here...) Okay, so I'm trying to solve a system of equations with a bunch of ranges: (Some number between 1.2 and 2.0) = (Some number between 5.5y and 9.1y) = (Some number between 5.4x and 10x) Where X and Y are ranges made up of two percentages (or...

I've seen a lot of the popular theories regarding how many dimensions there are, and it seems that they all have numerous spatial dimensions and one dimension of time. However, I haven't really found out much about why there is only ever a single dimension of time in any given theory. While I...

Ah, I see. Thank you! :)

Interesting... I wasn't taught anything about Maxwell in school, though I have heard of him somewhere before. So basically, gravity DOES have two components that behave similarly to the electric and magnetic forces, but they're so unnoticeable that it's rarely mentioned to us physics noobs...

In classical electromagnetism, Coulomb's constant is derived from Gauss's law. The result is: ke = 1/4πε = μc^2/4π = 8987551787.3681764 N·m2/C2 Where ε is the electric permittivity of free space, μ is the magnetic permeability of free space, c is the speed of light in a vaccuum, and 4π is...

Ah, forgive me. That was a grammatical ambiguity on my part. I meant to say that the particle is an excitation of a field, and the field does the actual interacting to give mass, not the particle. The way I phrased it was... not good. Yes, but what I mean to ask is does the particle do the...
