Would you please send me the numerical laplace inversion code of "de Hoog" 1982?

i use previous post link to derive again for weibull, the final integration seems can not be integrated,

any things need to notice?

Weibull
WeibullDist := (η/rho)*((x/rho)^(η-1))*exp(-((x/rho)^η));
WeibullDist := 1-summation((η/rho)*((x/rho)^(η-1))*exp(-((x/rho)^η)),x=0..k-1);
WeibullDist := int((η*z)*(((k-1)*z)^(η-1))*exp(-(((k-1)*z)^η)),z=0..1/rho);
WeibullDist := int((η*z)*(((k-1)*z)^(η-1))*exp(-(((k-1)*z)^η)),z=0..1/rho);

svp. Je suis débutant en Maple et je souhaite que vous m'aidiez à réaliser une courbe avec maple étant donné un ensemble de points, et non pas une fonction. Comment faire? merci.

Dear friends, 

I used Maple 13 previously, now am trying to install Maple 16 (Windows 7, 64bit, 2GB RAM), installation is ok. 

But when I start using the Maple, then I am getting an error message 'Waiting for Kernel Connection' and then Kernel connection not found. 

I disabled the windows firewall, and then reinstalled Maple  16, and again I got the same error.

what can I do now? how to cross that? its urgent for me. 

can someone write code to replicate this in maple.

Begin with a square and draw an octagon inside it, as pictured. Now draw a regular 16-sided polygon inside the octagon, like so

i'm guessing it'll use the polygonplot comand

expand(convert(simplify(GammaDensity, size),exp)),size)

www.stat.rice.edu/~dobelman/textfiles/DistributionsHandbook.pdf

i use the derivation of gamma in above book to derive density again, but fail

GammaDist := int((lambda^k)*(z^(k-1))*(exp(-lambda*z))/(k-1)!, z=0..t);
GammaDensity := diff(GammaDist, t);

GammaDensity := (b^a)*(x^(a-1))*exp(-x*b)/GAMMA(a);

Hi every one

I was wondering whether is it possible to make a subzone plot with in a zone or not?

some thing like this

 Thanks

Dear Maple users

I know how to plot surfaces in 3D. However now I have a special task: I want to plot a piece of a solid region in 3D, more precisely a transverse or logitudinal wave. I wonder if there is an easy way to do this in Maple? Any hint will be appreciated!

Regards,

Erik

i want an exaact answer(numeral) of an equation but I can't maple answer a realation that include sin,cos,root,z how can i simplify that to a number

Hi all.. Just purchased the maple 16 today. When i tried to enter a few equations, i relised that equals sign does not work for the equations. I tried '' ctrl+= '' but the letters on the screen get minimized that time. I just can't do the thning. My OS is win7. It does the job when it comes to calculate 2+3 or something like that. You get the answer when you press enter. But when it comes to variable eq.s like x+3=2 or 2x+3y=4 when you press enter, nothing happens. ıt just...

There is an animation of a falling rod in simulink here www.youtube.com/watch?v=lJEHzW-sp5c

How would that be presented in MapleSim? 

Also for the double pendulum, model in say if the bottom swing were to hit a wall?  Also model if two double swinging pendulums were to hit each other? 

How can I solve a pair of recurrence relations like this in maple 16?

{A(k)=1+((n-k-2)

Hi

Is there a way of importing data in NetCDF format into Maple 15? This format is very widely used in atmospheric sciences as a data standard for experimental data such as satellite-derived data.

Thanks

I have the following expression  f(t)=0.342 Dirac(t)+6.352 exp(-4t)+.0981 exp(-3.056t)  I want to convert it to a piecewise function of the form given below

 f(t)=0.342  if t=0

 f(t)=6.352 exp(-4t)+.0981 exp(-3.056t)      if t>0

when I applied                     convert(f(t),piecewise,t)
