Doom103 Posted January 7, 2009 Share Posted January 7, 2009 <Doom> Smarty <@SmartRutter> yeah? <Slyver> Be a ninja then. <Doom> Want a math question <@SmartRutter> uh idk <Slyver> TRISEXUALS!!! <Slyver> LAWL <Doom> if the permimeter of a parallelogram is 132,... <Javaman> 4! <Doom> the longest possible lenght of a diagonal is less than ____ <Javaman> uh... ...... later on <Doom> Let me finish the other problems and I'll bbl <Slyver> ... <@SmartRutter> like one question where i'd use calculus on would be like... someone has 200 ft of fencing to put around there farmland <Slyver> *sigh* <@SmartRutter> find the dimensions to make the most area <@SmartRutter> and of course it'd be a rectangular shape <@SmartRutter> so i'd label X and Y as two sides <@SmartRutter> A = 200ft <@SmartRutter> A = XY <@SmartRutter> therefore XY = 200 <@SmartRutter> Y = 200/X <@SmartRutter> A = XY <@SmartRutter> subsitution <@SmartRutter> wait no <@SmartRutter> that wouldn't help <@SmartRutter> ummm <@SmartRutter> A'=X+Y <@SmartRutter> (that'd be the derivative of the area) <@SmartRutter> A'=X+200/X <Doomer> We need a Doomest. <@SmartRutter> i'd have to solve for when A' equals zero <@SmartRutter> the reasoning is that derivative = slope, and a zero slope on a curve is a max or min value <@SmartRutter> think of a parabola <@SmartRutter> so 0=X+200/X <@SmartRutter> wait... <@SmartRutter> ok i got it now <@SmartRutter> -200/X=X <@SmartRutter> cross-multiply <@SmartRutter> X^2=-200 <@SmartRutter> -X^2 = 200 <@SmartRutter> square root <@SmartRutter> i forget whatever the sqrt of 200 is -_- <@SmartRutter> roughly 14.1421 <Kiba> smarty be quiet!!!!! <@SmartRutter> so back to finding Y... <Kiba> its not school time! <@SmartRutter> bah' Link to comment Share on other sites More sharing options...
