## fit correct resonance function...

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

## Maple doesn't find solution, but plots the solutio...

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?

## Symbolic taylor expansion...

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

## LSSolve...

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

## Plot Formatting and Special Characters...

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

## Numerical differentiation...

Is there an easy way to do numerical differentiation in Maple? I have a set of data, but would like to try differentiating numerically rather than fitting the data to a curve first. Thanks

## Need help with grpahing a function....

I have the function f(x,y)=(x^2+3y^2)e^-x^(2)-y^(2), and when I try to graph it with either plot 3d or implicit plot 3d I get nothing. Ant ideas what I need to do? Thanks!

## openmaple spash screen...

I've compiled and run the samples\openmaple\simple\simple.c from Maple 9.5. How do I get the program to run without displaying the spash screen? When running executables from a command line, this splash screen is annoying. The -q (for quiet) command line arguement does not work. Other command line arguements are evaluated by the api. Give it a non-existant arguement and it gives a usage reply as expected. The openmaple api spawns the spash screen found in bin.win\oms32.exe. Renaming this file causes an error: "Error launching OpenMaple splash screen." I can't delete the file, The error message is just as annoying as the splash screen.

## How do I enter variable data into a Maplet Table...

I want the data returned from a Maplet Evaluate to appear in a Table. I have listed below an example Maplet: with(Maplets[Elements]): > setdata:=proc() > Maplets[Tools][Set]('expdata'= [[5,42.6],[10., 31.5], [15,28.8],[20., 22.3], [30., 18.7], [45., 14.1], [60., 11.1], [90., 7.7], [120.,4.9], [180., 2.5], [240., 1.3], [300., .7]]); > end proc: > maplet := Maplet([ > # [BoxCell(Table([A, B], 'expdata'), 'as_needed')], > [BoxCell(TextBox['expdata'](3..30))], > [Button("OK", Evaluate(function='setdata()'))] > ]): > Maplets[Display](maplet); The Commented out "Table" line fails and the "TextBox" works OK. Is there a way to have this data appear in Table form?

## LSSolve...

how do i use LSSolve to find least squares solution to a function and plot it. Thanks

## Maple license-error: "System clock has been set ba...

Since I accidently changed my system clock to a time in the future and set it back correctly, I get an error when Maple starts. It's an license-error more specific: FlexIm error: -88,309 "System clock has been set back" Maple asks to reactivate, once done that successfully Maple says that after starting Maple again everything will work properly. But it doesn't work, I get once again the same error and the question to reactivate. The error is known by MapleSoft, I got this information: "FLEXlm checks the computer for files with a timestamp beyond the current date. If there are files with a creation date in the future of what the current system clock reads, FLEXlm will return this error. These files must have been created when the clock was set incorrectly. We suggest the user conducts an advanced file search to find the files that are causing the problem."

## assume statement in Maple...

Hi, I have a function that looks like: f := (x, y, z) -> -(y^x) + z; Now, if x = infinity, y > 1 and z < infinity, the value of the function f should be -infinity. How do I get that result using Maple? I was trying to use commands like simplify, assume and assuming, but I could not make it work. Any help would be appreciated... Thanks!
