Posted November 18, 2006 Alright, weird question, but it's for art stuff in school. =P We have to create a design for a tattoo, and now first they want us to look up all sorts of different tattoos and the origins of it and stuff like that. Anyone who knows any good sites about tattoos with a lot of information? I'm just posting this here cause some people might be bored and looking for something to do, and this isn't all that boring to help out with. =P http://www.bmezine.com for peoples experiences and ideas and there's a tattoo design category on deviantart.com stuff about tattoo history, http://www.tattoos-by-design.co.uk, http://en.wikipedia.org/wiki/History_of_tattooing Share this post Link to post Share on other sites
Posted November 18, 2006 I've never heard the term 'sahelmontane', but the Sahel is obviously the region of Africa you're talking about and montane is a high altitude grassland. See here. Share this post Link to post Share on other sites

Posted November 18, 2006 That makes a lot more sense, thank you! also, "sahel" in arabic means coast if that helps in anyway. Share this post Link to post Share on other sites

Posted November 19, 2006 Simultaneous Equations Okay, im usually good at these but ive forgotten how to do a couple of them. Please explain how to solve these with the 'elimination method' if that makes sense. 1) x+6y=9 2x + 3y=19 2)Add the Equations: 5x-2y=1 4x+2y=8 Share this post Link to post Share on other sites
Posted November 19, 2006 I: x+6y=9 |*2 II: 2x+3y=19 ______________ (subtract II-I) -9y=1 -->y=-1/9 then put -1/9 for y in one of the equations: x+6*(-1/9)=9 x=9+2/3 x=29/3 the second one is the same I think. Share this post Link to post Share on other sites

Yes, I get the same answers as you (but I doubled the second equation). For the second, you can just add the 2 equations: 9x = 9 x = 1 y = 2 Share this post Link to post Share on other sites
Posted November 19, 2006 i think youre right but i dont really understand Share this post Link to post Share on other sites
Posted November 19, 2006 i think youre right but i dont really understand Right: I'll start with the second question: 5x - 2y = 1 I 4x + 2y = 8 II I + II => 5x - 2y + 4x + 2y = 1 + 8 => 9x = 9 => x = 1 substitute into I: => 5 - 2y = 1 => -2y = 1 - 5 => -2y = -4 => 2y = 4 => y = 2 First question: x + 6y = 9 I 2x + 3y = 19 II 2(II) => 4x + 6y = 38 III III - I => 4x + 6y - (x + 6y) = 38 - 9 => 4x + 6y - x - 6y = 29 => 3x = 29 => x = 29/3 substitute into I: => 29/3 + 6y = 9 => 6y = -2/3 => y = -1/9 By the way, => means implies, and the roman numerals (eg. I, II, etc.) are numbering the equations so that I can refer to them. Share this post Link to post Share on other sites

Posted November 25, 2006 What's the formula in excel to get it to work out the difference between 2 cells? =ABS(A1-A2) But obviously replace the A1/A2 with the relevant cells. This gives the difference, the absolute difference (no negativity); I assume that's what you meant. Share this post Link to post Share on other sites
Posted November 25, 2006 Yup, that's right, cheers odwin. Better than the huge long formula my dad came out with. Share this post Link to post Share on other sites
Posted November 25, 2006 Does anyone know how to make excel draw a regression line of best fit through a set of points? I downloaded an addon that supposed to do it, but it didn't work quite how I wanted it to. Ideally, I'd like to apply different types of regression to different parts of the curve.
