Hello MathGroup, My last confession was... er... NSolve seems able to carry through significance arithmetic. FindRoot and NDSolve seem inable to do so. I would like to be able to solve the following equation for acCap[0] assuming cNapRatio->0 (sorry about the FullForm, but I had to rid the post of the one way Notations I made), does anyone know a way to get Mathematica to do this? Equal[Times[Power[Log[10],-1],Log[acCap[cNapRatio]]], Plus[Times[0.6107999999999999999`0.9956786262173576,cNapRatio], Times[-2.0360000000000000001`2.9999999999999996, Plus[Times[-0.0061540230743798795`0.9978339382434933, Power[acCap[cNapRatio],-2], Power[Power[acCap[cNapRatio],2],Rational[1,2]]], Times[Power[2,Rational[-1,2]], Power[Plus[Times[2,cNapRatio], Times[0.0410268204958658633`3.3010299956639817, Power[acCap[cNapRatio],-2], Power[Power[acCap[cNapRatio],2],Rational[1,2]]]], Rational[1,2]], Power[Plus[1, Times[Power[2,Rational[-1,2]], Power[Plus[Times[2,cNapRatio], Times[0.0410268204958658633`3.3010299956639817, Power[acCap[cNapRatio],-2], Power[Power[acCap[cNapRatio],2],Rational[1,2]]]], Rational[1,2]]]],-1]]]]]] -- Chris Chiasson http://chrischiasson.com/contact/chris_chiasson
