BehindTheMask Posted January 6, 2010 Report Share Posted January 6, 2010 A is such that A= s^2? Link to comment Share on other sites More sharing options...
Umbra Posted January 6, 2010 Report Share Posted January 6, 2010 V = As It's a function related to A and s. Link to comment Share on other sites More sharing options...
ShinyBlade Posted January 6, 2010 Author Report Share Posted January 6, 2010 you have a point Umbra, I was thinking the same thing but do you have to include number?come on what the answer Link to comment Share on other sites More sharing options...
Guest Posted January 6, 2010 Report Share Posted January 6, 2010 It would look nicer if the forums were LaTeX-compatible, but this equation is the one you're looking for: A = -(e^(pi*i))s^(SQRT((3^2)-(2^2)-(1^2))) Link to comment Share on other sites More sharing options...
ShinyBlade Posted January 6, 2010 Author Report Share Posted January 6, 2010 how does that varies with A and S Link to comment Share on other sites More sharing options...
BehindTheMask Posted January 6, 2010 Report Share Posted January 6, 2010 A is such that A= s^2? Doesn't that work? Link to comment Share on other sites More sharing options...

ShinyBlade Posted January 6, 2010 Author Report Share Posted January 6, 2010 WHAT? That doesn't make sense and direct variation doesn't have exponent Link to comment Share on other sites More sharing options...

Guest Posted January 6, 2010 Report Share Posted January 6, 2010 how does that varies with A and S You'll see an A on one side of the equation and an s on the other side. and direct variation doesn't have exponent Here, "direct" is used only to denote a positive association; it does not indicate that the variation is necessarily linear.

Skippy Canoe Posted January 6, 2010 Report Share Posted January 6, 2010 The area' date=' A, of a square varies directly with it sides,s write a direct variation equaton related to s and A[/quote'] I'll try. I think you may be looking for this. A=2s Because to find the area, you multiple one side of the square by 2. Hope I helped, and made this make more sense. :D I learned direct variation a while ago, so... Link to comment Share on other sites More sharing options...
Guest Posted January 6, 2010 Report Share Posted January 6, 2010 make sense but can you make it more clear? Nope, I'm afraid the equation doesn't simplify at all. In mathematics, simple things can require complex explanations. Link to comment Share on other sites More sharing options...

Skippy Canoe Posted January 6, 2010 Report Share Posted January 6, 2010 Brain fart... *facepalm* Well, then, he's probably doing the stuff you learn in Algebra 01, in which case, it should be in the format y=kx. EDIT: K could equal s, even though that would be an odd way to do it. y=s(s)? Link to comment Share on other sites More sharing options...
ShinyBlade Posted January 6, 2010 Author Report Share Posted January 6, 2010 what about A=as? Link to comment Share on other sites More sharing options...
Skippy Canoe Posted January 6, 2010 Report Share Posted January 6, 2010 No, because that wouldn't result in the area. A=(s)(s) is the same as A=s^2, just in the right format for what you're doing I'm guessing. You are looking for y=kx format, correct? Link to comment Share on other sites More sharing options...

EDIT: K could equal s, even though that would be an odd way to do it. y=s(s)?[/quote'] If he was going with the y=f(x) format like you're implying in the edit, it would be y = A(s).

Skippy Canoe Posted January 6, 2010 Report Share Posted January 6, 2010 @Umbra: But A is the range. Both y and A wouldn't be in it. The function of the function (cwutididthar?) would be to find the area from a side length. Link to comment Share on other sites More sharing options...
