I'm pretty new here, in maple and I think I'm not very good in math too but I would like to discover how to limit or set the domain of my x. Example: sin(x); I would like to set the type of the x to N (natural) and the type resulting to R (real). But after hours and hours of searches on google I subscribed to ask this to you, gentlemen :P Thank you everyone
Hi, I am interested in making the assumption T[0]<><><><><>
Bonjour, Je voudrais modéliser le vol d'une fusée à eau sous maple 11, je n sais pas par ou commencer. Merci d'avance pour votre aide.

Have you ever plotted a function in Maple and then found that the range you plotted it on wasn't really what you wanted? You can always re-execute the command, of course, but that means working out exactly what the range is for that interesting feature you want to investigate, and if you've made changes to the plot those will be lost. However Maple has the ability to zoom in on a plot interactively, without re-executing the command. The Axis Properties dialog lets you change the range numerically, but you can also do so using the mouse. Go to the plot toolbar and click on the Scale plot axes button (it looks like a red ball with an arrow). If you have an animation you will need to click on the word "plot" above the toolbar to switch from animation to plot toolbar. Now put the mouse in the middle of the plot and drag it. Dragging it down will zoom out, increasing the range; dragging it up will zoom in. The Translate plot axes button lets you 'pan' i.e. move the centre of the axis ranges without changing the range size.
Hi, I am trying to create a sheet to show the derivation of 2nd and 4th-order function derivatives as part of a 5-point finite difference scheme for a 1-D model (a continuous beam on an irregular foundation). I have isolated 2 simultaneous equations by using Taylor polynomials and would like to cast these in matrix form and then solve for each of the D-operators symbolically. Is there a simple way to do this or do I have to work with the ops manually? thanks for any help, Neil
I have difficulties understanding why exactly Maple finds the question difficult to answer. First attempt: assume(a>0); a:=sqrt(b^2); eval(a, b=2); (1/2) / 2\ a := \b / (1/2) 4 I suppose the problem is that after the assignment Maple forgets the assumption a>0(?). Is there a way to make _real_ assumptions on variables, which Maple will not forget and possibly warn me if I try to violate?
Dear All, I have two odes, dX/dt = -X(t)*Y(t) and dY(t)/dt = X(t)*Y(t) I can solve these numerically using the following code: eq_1:=diff(X(t), t)=-X(t)*Y(t); eq_2:=diff(Y(t),t)=X(t)*Y(t); IC:={eq_1, eq_2,X(0)=10,Y(0)=1}; F:=dsolve(IC, {X(t),Y(t)},type=numeric, method=rosenbrock); h := theta->eval(X(t),F(theta)); h(1); However, I would like to add perturbations at specific time points. For example, at t=10, set X=5, or at t=15, Y=0. How should I do this in maple? Note: my actual situation involves a 100 odes. Thanks, Colin
How can I write a recursive algorithm on maple wich gives me the fibonacci polinomies knowing that: F1(x) = 1 F2(x) = x Fn+1(x) = xFn(x) + Fn−1(x), n = 2, 3, ... i think it's easy but still can't do it...if anyone knows help me please
I subs (a^2=4b, expression) and get (1+b)*x^2+a*(1+b)*x+b(b-1)+2*b visually, (b+1) is a factor of the polynomial but the machine refuse to recognise this, I tried /(b+1), collect, expand and simplify and all failed. This is quite a frustration to new user who just want to get things done quickly!
Hello, everyone! Given a polynomial: f := x^2*y + 10*z*w + 2*a*t I would like to know how many different variables appear in f. Is there a command I can use to do this? My actual polynomial is more like: f := x[1]^2*x[2] + x[127]*x[3] + ... Any help would be appreciated! Thank you very much, and happy holidays! Best, Susan
I am new to the Maple v.11 world and trying to figure out how to do things. I'm getting lost with the instructions in the help screens. Here is the problem: Can somebody show me how to enter this into Maple. Find the probability of an observation falling within one standard deviation of the mean. A Poisson distribution with [lambda]=16. Two other questions are normal distribution with mean=20, and a gamma distribution with [alpha]=4 and [theta]=5. I'm sure that if I can figure out one of the problems, I can figure out the others. Somebody please show me how to enter the problem
Hi I have data I want to fit it I do not know the model function I know only that the relation between X and Y is non-linear and there is six parameters I want to know their values from the fitting.can I do this using Maple or it is impossible. this is Maple work sheet: Download 7089_X0165.txt

Is it possible to execute an fsolve() for the equation as given below? I have not been able to get it to work thus far. Thank you for your support. Excel cell formula: =Maple("fsolve(2*(2*EllipticE(&1)-EllipticE(sin(beta),&1)-EllipticK(&1))+2*EllipticF(sin(beta),&1)=tan(beta)*sqrt(1-&1^2*sin(beta)^2),beta);",I14)
I have looked around and can't seem to find anything. Something simple that would provide the number of days eleapsed between two date/times. This comes in handy for radioactive source decay calculations. Thanks, GL
