Dear Prof

i need a maple code for solving non linear equations by variational iteration mthod.please help me in this problem.

with best regards

I need to solve the below nonlinear equation for n numerically, assuming taut and taum are between zero and one, not inclusive of zero and one. 

I first used "solve(EQN,n, useassumptions)assuming taum>0, taum<1, taut>0, taut<1;", but no solution was generated. I thus removed useassumptions, and used "solve(EQN,n);", but I received the message "Warning, solutions may have been lost" from Maple. How to solve this problem?

Why

fsolve((a^2-1)/a, fulldigits, -4..4, a=9.0)

say that ' a=9.0' is invalid range?

P.S. If answer exist it also should work with avoid option.

P.P.S. Arguments processing of fsolve is terrible. After formatting and trying to understand eval(fsolve) my brain blows up. Why maple has no universal argument processing utilite avoiding dozenz of 'ifs'?

Is it somehow possible to apply the Explore command to a procedure with numerical parameters?
It would be convenient in some cases. For example, let us consider  the following  procedure:
K := proc (alpha, theta1, theta2, sigma, n::posint)
uses Statistics;
t[alpha] := fsolve(CDF(RandomVariable(NormalDistribution(0, 1)), -t) = alpha, t);
 beta := evalf(CDF(RandomVariable(NormalDistribution(0, 1)),
t[alpha]-sqrt(n)*abs(theta2-theta1)/sigma));

As far as I know, exporting an Array or Matrix of plot is not directly possible in Maple 15. Is that right? Is there a workaround?

However, I read a suggestion by dskoog that seemed to work:

I need to plot two sets of data versus the same X- axis. For instanse, I want to plot <1,2,3,5,6> and <23,51,54,65,24> versus X-axis of <1,2,3,4,5>. Does anyone know how I can do this? Thanks for your kind help.

Code must not work in such way. See attach. solve_test.mw

What is the advantage of Maple over Mathematica?

Thank you for your comments.

How opening maple twice and execut 2 programs at the same time. If possible.

Thanks

How to make Maple recognize that: sin(x) +sin(x+Pi/3) is equivalent to sqrt(3)sin(x+Pi/6), and various variants of this expression involving sine, cosine, constants equal to Pi/3, Pi/6, etc? I can do it using the subs finction, but this involves finding the equivalent by hand for each variant. Thanks.

Maple sometimes decides that the plot needs to be plotted from -infinity to infinite when I do not want it to.  How Maple decides to do this seems inconsistent.  Some plots having a maximum value on the order of 10^3, get plotted on the infinite scale, while others do not.  On the other hand, other plots having a maximum value on the order of 10^-32 get plotted on the infinite scale, while others do not.  In any case, I would very much like to know what...

I am trying to evaluate integral (-1/rho)*del (p)/del (x) dy within the limits y=0 to y=delta (x). For that I first evaluated (-1/rho)*del (p)/del (x) and stored it in res2. Then I tried to integrate it w.r.t dy within limits 0 to delta (x). I wrote the following Maple lines for the purpose:

Te := proc (x, y) options operator, arrow; T[inf]+(T[w]-T[inf])*(1-y/delta[t](x))^2/(1+2*A*H/delta[t](x)) end proc

PDE := diff(P(x, y), y)-rho*g*beta*(Te(x, y)-T[inf]) = 0

I'm thinking about getting a new laptop (since the current one is kind of outdated). I use a lot of Matlab, Maple and Mathematica and will be doing come cfd computations. I found two laptops which, for the same price, only differ in processor and screen size. One features a i7-2620M and has a 13' screen and the other a i7-2670QM with a 15' screen. What I need to know is if the difference between processors is significant enough for me to turn a blind eye on portability ...

I was trying to solve a PDE with boundary conditions and maple 15 didn´t give no answer. 

Is there something wrong? I'm just trying to solve a textbook problem om electrodynamics in maple.
