i think it should be exp(1)^x


is this want you need?

this is really helpful


i might just use "0.1" method

i think all of you got a nice idea of doing it however i think may be what my friend what to do with maple is : suppose he has got several set of data a:=set of data b:=sin(set of data) c:=cos(set of data) 3d plot is there any simple way to do so? not like smooth plot liek plot( sin,1..12), thanks anyway ====================== For Maple on MAC how do i open classical worksheet if it is not on the desktop?

use the theorem to test the ODE ,the solutions are NOT unique

however maple gives me a unique solution?

LibraryTools:-Save(mayan, "/home/joe/maple/lib/mayan.mla"): should i change that slightly to get rid of the waring "Error, (in unknown) file or directory does not exist"?
really sorry to bother you however i cant resist such an intersing topic === libname := "C:\\Documents and Settings\\CasperYC\\Desktop\\mayan.mla", libname; mayan(123); then run your new procedure still Error, (in unknown) file or directory does not exist the mayan file is on my desktop...
>libname := "C:\Documents and Settings\CasperYC\Desktop\mayan.mla", libname: > mayan(123); then copy your new procedure still get Error, (in unknown) file or directory does not exist
return y[N+1]; basically i uderstand your procedure now however i cantfigure out the use of "return"and why it's index is N+1 since the rest "y"s have index small "n"
that's only a small part of a project i am doing it for fun. you can find the whole exercise on the math department of the university of oxford. i haven't learnt this perticular topic so it is kind of hard to me.

contourplot(f,x=-2..2,y=-2..1,color=red,contours=[-1,-7/16,0,3/4]); can i ask why is this order contours=[-1,-7/16,0,3/4]);? cheers
thanks how about exercise 7?
it's been solved thanks
