Assuming that you want to show the steps in solving your equation, try this, restart; eq := [z = (1+y+y^2-y^3)/(1-y)^3]; eq := eval(eq,z=0.8); solve(eq,y); Hope this helps J. Tarr

Alec, What was the reason for the double back-quotes before the second term on the lhs of your example, please? They seem to make a difference only to the way that term appears after the equation is evaluated - perhaps by %; after the second line of your example. Many thanks, J. Tarr

I have no problems with exporting worksheets as RTF using Maple 10.04 and XP Pro SP2 and opening these with MS Word. Hope this helps you isolate the problem, J. Tarr

Maple V Revision 3 (and Revision 2, I believe) used the .ms extension. If you can get hold of a copy of Maple V Revision 5.1 this can update the code in Revision 3 files and you can save then them with the .mws extension. A further pass with Maple 9 (you may have to use cwMaple) will update the code in the Maple V R 5.1 files and you can then save them with the latest .mw extension. The files are then usable with Maple 10. If your Maple retailer has copies of these old versions of Maple, he/she might do the job for you as a gesture of goodwill. Or, perhaps, Maplesoft would do it. You can but ask. Hope this helps, J. Tarr

The results from commands in the Statistics package mentioned in this thread and some related ones are compared in the worksheet linked below with those from the "old" stats package. All the Statistics commands tested gave correct results with two exceptions. These were the Variance and StandardDeviation of a sample obtained from weighted data. There is a bug here. There is an inconsistency in the use of Bessel's correction for a (small) sample as between both the Variance and StandardDeviation and the second Moments about the Mean in the Statistics package. J.

Maple can't solve your eq1, unless you tell it the values of the constants T[1] .. T[n]. Hope this helps. J. Tarr

Try something like this, altering n to suit your requirements: restart; with(LinearAlgebra); n := 7; A := IdentityMatrix(n); for i from 1 to floor(n/2) do A := RowOperation(A,[i,n+1-i]): end do: peridentity('A') := A; I am sure it can be improved upon, but in the meantime, I hope it helps. Incidentally, where is "peridentity matrix" defined? J. Tarr

You could also try this: plot( sin(x), x=0..2*Pi, axesfont= [SYMBOL],tickmarks=[ [0="0", evalf(Pi/2)="p/2", evalf(Pi)="p", evalf(3*Pi/2)="3/2 p",evalf(2*Pi)="2 p"], default],title = "Plot of sin(x)" ); See ?plot,options for tickmarks, axesfont, font, title and much more. Hope this helps J. Tarr

Try substituting the following in your code: #Generate functions of u for different values of T for q from 2 to 7 do u||q:=subs(T=q*1000,u); od: #Plot these function on one graph suitably scaled. nu := 10^15*x; plot({u||(2..7)},x=0..2,title=`Energy Distribution Plots for T=2000K-7000K`,labels=["e+15",""]); Hope this helps.

Your premis should read 1/tan^2(d) = 1/(sec^2(d)-1). Perhaps the relationship between sines and tangents you want is sin(d) = (2*tan(d/2))/(1+tan^2(d/2)) Hope this helps. J. Tarr
