Sameer Posted November 21, 2006 Report Share Posted November 21, 2006 What do you need help with, Noz? My housemate does Maths and uses Maple* a fair bit so I could ask him.*not sure what version, mind. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted November 21, 2006 Report Share Posted November 21, 2006 9.5's where it's at Only just started to use it though so can't help I'm afraid, sorry Quote Link to comment Share on other sites More sharing options...
nb88 Posted November 22, 2006 Author Report Share Posted November 22, 2006 Basically, got a piece of coursework and its all going well apart from this one problem:I plotted a graph, (a x^2-b x-c) (e)^((-1/5 dx)) and used (y(x) = (a x^2-b x-c) (e)^((-1/5 dx)) to define it as y(x)i now have to find the roots (points at which x = 0). I can see 2 on the range of my graph, but when i use fsolve to try and find them, it only gives me 1 value:> fsolve(y(x) = 0, x) -0.6902380714I dont understand why it doesnt give me both? I've only used maple in 1 lecture so i dont know what im supposed to type to find both roots... im sure itd be the same on all the maple versions...coursework is due tomorrow Quote Link to comment Share on other sites More sharing options...

Same as a calculator, it only gives you positive tan values etc etc when there are -ve as well. Same as square root on a calculator Quote Link to comment Share on other sites More sharing options...

Same as square root on a calculatorIt says on my cwk sheet: 'If it does not give all the roots, check the Help to see how to find them'. Looked through help for hours...not found anything... Done everything else pretty much now and done all the descriptions, just this thats bugging me. Quote Link to comment Share on other sites More sharing options...
