## ''How to plot a curve ?"...

Please Help! I am a beginner in using maple, I am getting  error in theta(k+2).How to get  m1,m2,m3 values from theta(k+2) and how to plot a curve theta(eta) like,f(eta). pp_DTM.mw

## "Copy As Image" not an option any more?...

Hi there,

I updated to Maple 2022 recently. One problem I am facing is how after I write the code and get the output, which can be text or equations or plots, etc, when I try to copy it to MS Word for example, I don't have the option of "Copy as Image" anymore. This option was available in previous versions. So was it taken out in this version? If yes, what's a subtitue for that?

I am using Maple for a school project and need to be able to copy the 2D output to MS Word just like the previous versions of Maples did.

Regards

## Non-projected vectors: Is this a Maple term (and r...

I'm trying to get familiar with the Physics package. It's huge.  Since I know vector projection, I can guess what a projected vector might be. But what would a non-projected vector be in a physical context?

A web search for non-projected vectors was unsuccessful.

My best guess is that non-projected vectors in Maple are those where no coordinate system is specified for vectors in an expression for a physical law. Like here in Maxwell equations. Am I correct?

To distinguish between these vectors the Physics[Vector] package uses an underscore “_”.

If my understanding is correct so far, I have three questions:

• Can I replace the unit vectors of implemented projected vectors to something else (e.g. _i to e__x)
• Is it possible to define projected vectors beyond what is implemented in Maple?
• Can I use the packages VectorCalculus and Physics[Vector] at the same time?

## How the Integral can be solved?...

Hi friends

Could you please give hints to solve the integral

int(exp(I*k*x)*sech(x),x=-infinity..infinity)

Thanks

## Error, missing operation after conditional break...

I am trying to run this procedure, but am getting an "Error, missing operation", highlighting the conditional break:

``````is_prime := proc()
local i, x_check;
printf(`Enter an integer to check if it is a prime number...`);
if x_check<=2 then
printf(cat(x_check,` is a prime number.`));
else
for i from 2 to x_check-1 do
if (irem(x_check,i)=0) then
printf(cat(x_check,` is not a prime number.`));
break 2;
end if;
end do;
printf(cat(x_check,` is a prime number.`));
end if;
end proc:```
```

If I don't include the integer, I am able to run the procedure, but it does not function like I would like it to. I am running Maple 2022, and can sucessfully run the example conditional break code in the Help. What is wrong with my use of break?

Does Maple 2017 have cwmaple.exe?
