## How to apply the simplify units command to everyth...

My question is how do i get Maple to simplify every calculation that involves units automatically, right now i have to do this manually for every single one.

For example: This values all come from variables wich have units assigned to them.

Then i hit right click, Units -> Simplify and i get this:

## How do you truncate a power series?...

I am using dsolve(..., type = series) to solve differential equations in the form of a power series. I plot these power series with different orders to observe how they converge. I use quite large orders (25 or even 50), and generating these solutions is slow.

I would like to generate power series with order 25, for example, and then truncate it to order 24 directly, instead of having to call dsolve a second time. I was hoping this could be done somehow using convert...

Hi All! I need your help.

I use the Student:-LinearAlgebra:-LynearSystemPlotTutor() and i can print it with:

Hello,

I'm under pressure to complete the following plot for a Masters project. I just can't seem to find where the errors are. I'd be very grateful if anyone can help.

## how to define a correct Commutator relations with ...

Hi, friends

The physics package was provided a good tool to compute Commutator or anticommutator relations. Here, I met some problems.

Example 1:

restart: with(Physics):Setup(mathematicanotaion=true):

Setup (op={p[x],p[y]},p[z]):

alg:=%commutator(p[z],p[x])=2p[x], %commutator(p[z],p[y])=-2p[y], %commutator(p[x],p[y])= p[z]

## Problem with Mean in Maple 14 Statistics package...

Why the "Mean" command of the "Statistics" package gives the correct result with MAPLE 12 and MAPLE 13 and not with MAPLE 14 ?

restart;
with(Statistics):
X := RandomVariable(('Uniform')(-1, 1)):
Y := RandomVariable(('Uniform')(-1, 1)):
pdf := simplify(PDF(sqrt(X^2+Y^2), rho)):
R := RandomVariable(Distribution(PDF = unapply(pdf, rho))):

The mean may be computed using (the answer is correct)
int(rho*pdf, rho = 0 .. sqrt(2)):

## fastest way of computing an integral numerically?...

I'd like to numerically compute integrals of the forms:

int(exp(-t)/((-3+2*exp(-(1/10)*t))*(-3+2*exp(-(9/10)*t))), t = 0 .. infinity); evalf(%)

where there are much more terms in the denominator, e.g.,

Int(e^(-t)/(product(-3+2*exp(-.1*(1-.1)^i*t), i = 0 .. A)), t = 0 .. infinity); evalf(%)

for some positive integer A. Even when I have three terms it takes so long... So how do I compute such integrals numerically with maple; what's the efficient...

## How to import a photo to Maple...

Hi everyone

I'm new to the forum, but I hope you can help me with a problem concerning import of pictures to Maple. I'm working with diffraction from a rectangular and circular aperture. I haven't made the experiment yet, but I've thought about taking some pictures of the diffraction pattern and then use Maple to calculate the intensity of the light to make a three dimensional plot (intensity as a function of position).

Right now I just want to import a picture...

## Maple window frozen - shows only a grey screen...

You would have thought I'd have learnt to make sure I've saved my work by now.

I've spent the last 4 hours or so working on a worksheet on Maple, without saving it once (I know, I know). It started acting slow-- by which I mean it was talking a while to actually type things, as opposed to running calculations-- and then the screen suddenly went grey, froze, and now my cursor turns into an hourglass when I mouseover the window.

It's been this way for the past 10 minutes.
