## LSSolve...

I have the fuction F/sqrt(m^2*(omega^2-omega_0^2)^2+b^2*omega^2 and i need to fit data to it using the LSSolve command, i have no idea how to do this any help would be much appriciated. thanks.

I would like to hyperlink or insert acces to other program files. I can do this in MS Work and Scientific Notebook. Ex. I can execute Vpython simulations, audio files, saved web pages, etc. Thanks

## Geometry - how to draw triangles, circles, polygon...

Hi, can you advise how I can draw geometry objects like circle, triangles, polygons, angles in triangles, etc accurately -- I need the gepmetric shapes to be to-scale -- in other words, if I need an angle at 50-degrees, I don't wish to eye-ball it, but I really need it to be 50-degrees. Thanks!

## pascals triangle...

Hello, i'm a father and my son is at school, he asked me if I could give him some help on his maple project. He has to write a pascals triangle using List, is there anyone who can help.Thanks, Ronald.

## critical points...

Hi, I would like to find the critical points of a formula like: f(x,y)= 5e^((-x^3)-xy/3-y^2/3)cos x cos y But I don't know how to do it, can someone help me? regards, Patrick

## Corelatind data using Matlab. Finding the best fit...

Hello Memebrs, I want to write a code in Matlab, that will find a best fit. I have 4 columns of values. The Red, Green and blue values and in the fourth column the temperature values. I want matlab to intelligently find me the best corelation between the RGB values and Temperature. Any pointers as to how i can go about doing this. Ofcourse the main goal is to get the best fit with minimum error. Thanks in advance.. (here is some raw data, it that could help) 17 13 28 380 15 10 28 386 25 14 40 392 17 13 38 398 9 8 23 404 3 2 7 411 7 9 19 418 10 12 21 426 3 4 13 434 0 0 6 442

## cant calculate expression in TextField/Box...

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?

## Taylor Polynomials...

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

## Algorithm...

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.

## Strange Animation Behavior...

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, M. Hamilton

## Problem with CodeGeneration option...

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:=
