This problem agonize me for a long timeand i cant to solve it.
For example, in one TextField in maplet i want to insert e.g. "0"
and in second TextBox to get result of e.g. cos(0) apropos "1".
But i get cos(0). I was try to solve this with eval, evaln and evalf command but nothing get.
Won't to insert number in one TextField and to calculate e.g. cos()
in other TextBox. Someone know how to?
program:
restart;
Calc:= proc()
global theta:
cos(theta);
end proc:
with(Maplets[Elements]):
DKP:= Maplet(onstartup = A0,
Window[W1](title="DKP", [TextField[theta](),TextField[result](),

How can I create a menu with Maplet Builder?

I need to plot the taylor polynomials of sin(x) up to degree 7, i know the functions and i inserted this command: plot({f-g+h, f, f-g+h-i, f-g, sin(x)}, x = -Pi .. Pi, y = -2 .. 2, title = "Taylor Polynomials of Sin(x)") where f g h and i are simple taylor polynomials. Now my question is i need to label the graphs, i tried using legend="..." but i get the error: Error, (in plot) the legend option cannot be used when ploting a set of objects so how would i do this? any help is appreciated

Hi. Many thanks for your time. I'm just trying to get some help on getting maple to calculate the values in an algorithm. Can you suggest where I can access some help pages? The algorithm consists of 3 interacting elements; alpha(i), gamma(i) and epsi(i). The object is to compute the first however many (say 1000) iterations of epsi(i). To do this you need the first however many iterations of alpha(i) and gamma(i). Each value 'p' represents a different algorithm. (ie. a different set of the algorithms alpha (i), gamma (i), epsi (i). I put the *** around the information which is redundant for my purposes but which may be useful in terms of programming.

Hello, I am trying to animate a solution to a set of coupled second order differential equations but I am getting what looks like the concatenation of the velocity with the graph I am plotting (note the bump to the left of the solitary wave). I am also looking to make it a bit more precise so I do not see all the distortion as the animation runs, I believe this my be due to the approximation of the numeric solution. Any help would be greatly appreciated.
Sincerely,

Hi, I've been working with the Maple recently. And couple days ago I've just stopped, why, I don't know how to generate the C code from matrix, using the CodeGeneration with this Optimize option. But where exactly the problem is:
For example we have a matrix H:=

Hello was looking around the net for a guide to help my and then I fell over your lovely site here ;) I have a small problem, if I insert a prompt in a "Document Sheet" in Maple 10, then I can't remove it again ? The > is like rock solid, can't delete, backspace, 2nd mouse or anything to get a normal empty line back ?? Thx in advance for your help ..

Hello.
I hope someone has a trick for me:
I have the following polynomia:
>restart:with(linalg):
>g:=(x,y,z)->5*x^2+8*y^2+5*z^2-4*y*z+8*x*z+4*x*y;
My question know is how to create the following list (for use with subs, eval or similar:
>L:=x^2=5,y^2=8,z^2=5,z*y=-4,x*z=8,x*y=4;
I can offcourse just enter the list, but this is not possible when I have very large polynomias.
I tried the "coeff" and the "coeffs", but was not able to get what i wanted.
Any suggestions?

How do i show data points on spline on same graph and integrate to find the area under curve.
i have the spline and the data but cannot get them on the same graph

How do i use LSSolve to fit the correct resonance function to a set of experimental data, thanks

Hi, I want to make the following integration: R0:=int(-P_m*(-1+exp(-30*Di_d/P_m/(1-u*P_m^v+q*P_m^r)*q*P_m^r))/kappa*exp(-P_m/kappa), P_m=0..infinity) Di_d, u, v, q, r and kappa are all constants, which are all positive parameters. P_m is the only variable (so R0 is a function of P_m). As the solution of the integration Maple gives just the integral sign from 0 to infinity and the unsolved equation. Does this mean that Maple is not able to find the solution? So it is not possible to do the integration? However Maple is able to plot its solution. How is this possible? Is the plotting just an approximation?

Greeings, Can Maple write out the symbolic form of a Taylog Series? Thanks in advance, David

How do i use LSSolve in maple, i have a set of data and a formula and i need to use LSSolve to fit a curve to the data and then plot it.
thanks

HI,
I am a Masters student, engaged in research with a small applied maths component, nothing more complex than matrix calculus.
I am currently using Scilab, but would like to get a student version of one of the following:
Maple
Mathematica
Matlab
Why should I choose Maple? I'm not looking for marketing BS - I can get that off the websites, but I am looking for genuine opinions and facts from people who have more experience than me with these packagaes.

Hi All you folk with more experience than I have. Question 2. Is there a way to place the legend in a graph next to the graph rather than below it? Question 3. How can I create my own own variable names... I want to place a ˜(tilde) above a character, present task requires the ˜ above a 'v'. Question 1. This was answered unsatisfactorily in "Symbolic characters in plot titles". I have attached a worksheet with my quetsions. Any help will be appreciated :) Thank you Al
