## Maple code input drifts right...

Hi quick question.  When I am writing in maple 2D input the next line seems to add a space and I have to manually go and take the spaces out.  Is there a quick fix for this?

Thank you.

## Numeric evaluation with Units...

Hi!

I have solved an ODE and defined some physical values with Units.

Now i want to calculate the speed at a time of 120s for example, but the evalustion does not show a result.

I want to have a result like ve=63m/s for example and  not ve=v(120s)

Further more if calculating the complete worksheet, the diagramm settings are set to default and i can not see the curve like before. Is there a way to keep user defined settings?

Has somebody an idea what's going wrong?

Calculating completely without units works.

## Maple 2017 Copying matrix gives _rtable...

Hey there.

And in the new version, whenever i want to copy a matrix from a result, it gives me an _rtable, and a number. The result is the same, but it makes it harder to read and i am not able to edit values in this copied matrix.

How do i change this?

hi..

I dont know why ''Y'' in this code does not calculate?

Also in Determinant  should exist term ''Omega''!!!

however this term not apear!!

thanksZrO2.mw

I'm defining forces. The only thing I changed is x to y for one particular piece of an equation. I copied and pasted it so I don't see why it's not working.

## Maple 2017 formatting issues ? ...

Hello all,

This is my first time with Maple, I have been a student of Mathematica for 7 years. I purchased Maple to learn a new software and I have heard great things about it. I somehow dont feel the flexibility of Mathematica in Maple documentations. It seems to be a bit constrained and not very straight forward in some aspects. Please correct me if I am wrong and also point out to tutorials or documents that I should be looking at before nose diving into Maple.

worksheet example here:

I have faced 2 simple problems which I think is a bug in some form, or I may be wrong. Please advise.

1. How do I insert Equation 7 before Equation 6? The worksheet wont let me do it.
2. Why are 'and' and 'in' bolded automatically in SECTION format?

## plot a equation with complex in bessel function....

hello experts,

I was using maple for a physical  problem,

and things turned very complicated with a equation with bessel function in it,

like this and,

which include complex,

the whole equation is as followed:

the variable is f and RV,,dependent variable is RV.

how am I supposed to plot RV when f=100..4000?

it is certain RV has real part and imaginary part,maybe i need a 3Dplot?

please let me know if you have any idea.

best regards,

want to plot the relationship between RV and f,but how?

## How to label a big math expression on vertical axi...

How to label in inline math mode. I tried labels = ['theta', Typesetting:-Typeset(cos(1/theta)/sqrt(1-theta^2))] which gives a big expression on Y axis spreaded in two lines. But i want to label one line as in latex $\cos(1/\theta)/sqrt(1-\theta^2))$ . Is there a way to do it ?

## What does this syntax for assigning names to varia...

I'm new to maple and I'm trying to write code in worksheet mode with some source code I have, I don't understand some of the syntax though, like the next:

m,  mass

J=m*r^2; Inertia

m and r are variables, so does this syntax mean that after the comma I set a name or label to the variables? because I tried to follow the same logic with 2d input math but it doesn´t work.

## "expand" command does not act as it should...

Hello!

I am working with the Maple 18.02 version. I just want want to perform a basic polynomial expansion using the command "expand" and it does not respond as it should according to what Maple Programming Help says it would. For example:

Maple Programming Help says:

I get:

.

Also, one sees that this isn't even true, as x(x+2) + 1 = x^2 +2x +1, which is not equal to x^2 + 3x +2.

Moreover, maple tells me it is equal..:

What is going on here? I woul like to get the full expanded form (without factors). Also, this is obviously not true, or maybe Maple means something else by x(x+2) +1...

Thank you!

## Is there a way to make Maple output display explic...

Hi there,

I'm new here. My first question:

Is there a way to make Maple output display explicit multiplcations signs in 2D-math?

Example:
When you enter 5*2^x Maple will output . Is there a way to make Maple display the multiplications signs in output in stead just implicit multiplication signs (i.e. whitepaces)? (I would settle for Maple display all multiplication signs in output - not just the ones which are made explicit in the input.)

I searched this site. No luck. I looked into "Typesetting Rule Assistant", but I couldn't find a way to alter the output of multiplication sign (*).

Can you guys help me?

Kind Regards,

Jens

P.S.: I'm a teacher from Denmark. We use Maple before college/university for a lot of pupils. Some less competent pupils have a tendency to overlook the whitespace.

## annoyance bug using single quote in division...

A bit of an annoyance.

typing 'numerator' / 'denominator' generates an error.  The first quote never gets automatically grouped as it should.

Two workarounds.  The first is to move to, and delete the first quote and re-enter it again in front of numerator.
The second is to use brackets, although one shouldn't have to.
