Hi everyone,

While I am getting more and more comfortable with the document mode, I have some questions regarding the document block feature:

- What is a document block good for anyway?
- Why not have the whole document in one block?
- Can one join two document blocks?
- when do I "remove the document block"
- How can I make sure that say an informational 2-D math expression inside a document block never gets executed?
-- Can I still...

can you help me about multiplication :

when I type a multiplication in Maple 15, Can I skip the multiplication sign between two variable?

for example : instead of type  x*y , could I type xy ?

Hi..I need to plot the slope field for a diffEQ and having problems. I have a Maple 14 program that I just had to reinstall due to a virus and hoping that isn't the problem.  I'm very new to Maple and I'm not a good programmer, so any light you can shed on my problems would be much appreciated.  When I enter the problem, I don't get any error message or anything...just a blank return!  This is what I tried:

with(DEtools):

DEplot (diff (y(x...

I'm trying to plot a function but I recieved the error :

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct.

It seems its simply because the function is a bit complicated, because I get the correct plot with eaither part of the function separated. Its my function:

Hi all,

I am now helping with the first year maple session in my university. Recently, some of the student are learning both 1-d and 2-d input.

Now we have something like this:

Is this some sort of bug?

I know it has something to do with the 1-d or 2-d or math input, but in short, that's what happens.

Thanks!

There are many ways to enter the second derivative in Maple.  Except for some silly reason I am stuck trying to figure out or find out how to enter it in 2d math form. 

d²    f
^---
dx²

Entering it like d^2 (right arrow) f  / (dx^2)  is not the right way to enter it.  What is the right way?

On the topic of the quality of rendering of (2D) Math on websites, could that also be re-examined for both Mapleprimes and Maplesoft's on-line help system?

Right now the on-line help has pages with missing images in Examples. For example, the `int` and `sum` on-line help pages, here and here.

On that

Quite often, when plotting an expression in involving trigonometric functions applied to (a rational polynomial of) the main variable, it is desirable to have the major ticks along the x-axis be labeled by multiples of Pi. In particular, it can be much more appealing to have those tickmarks be labeled with short rationals multiplied by the 2D Math symbol π.

If you want better performance then don't use 2D Math mode to enter procedures which call  `.` (dot).

The following timings are not the result of the order in which the cases are performed. The timings stay roughly the same if the blocks delimited by restarts are executed out of order.

This sites needs better rendering of 2D Math.

Here is a sample from the Wikipedia page for Maplesoft, from the pdes example section. The image on Wikipedia is quite nice (it's alt-tags have LaTeX code, which may be a hint).

Here's my first attempt at posting some 2DMath on this site.

First, I will paste directly from 2D output in a running Standard GUI Maple session.

BesselJ(0, x)+GAMMA(Psi)-sqrt(abs(omega))

Are the following paragraphs from the new Mapleprimes Style Guide supposed to contain marked up 2DMath or interpreted Maple result, because right now they don't.

See http://www.mapleprimes.com/help/styleguide

"For example, if you enter <maple>x^2/y^2</maple> you will get this image: x^2/y^2

Any Maple syntax will appear, so you can get complicated and enter this: <maple>sum(cos(x^2)/sin(exp(y)),x=1..infinity)</maple>
which then appears as this image: sum...

Does anyone see the Maple 2D Math output in the replies to this post?  What I see is a lot of Maple Equation markers.

There was some recent discussion about Maple's Standard GUI having two parsers. (See here, and its parent.)

I've been accumulating a list of some differences between the parsers of 2D Math and 1D Maple notation, for the same given pasted input.

In particular, I'm interested here in differences...
