question1:When I Input a complex expression,the superscript is sometimes acceptable

I copy a good-form letter with superscript to the destination box,but the superscript is too high,a little far away the letter,and in the whole expression,they're not the same form!

How to solve it？

Hi,

Is there any way to generate a list of symbols from the equations in the worksheet automatically? If not is it possible to attach a note to each symbol and when the cursor is moved over it the description is displayed?

It is annyoing to generate a list of symbols manually.Any help is appreciated.

Regards,

Hi, I have function like t^2+t+1 and I want to differentiate it with respect to time and set it an a new function, in order to calculate its derivation at some points. for example: a1_Func := (t)-> t^2 + t + 1; a2_func:=d/dt a1_Func(t); it works fine, but I can not call a2_func(t) at t=2 sec for example and it gives me an error saying "Error, (in a2_Func) invalid input: diff received 2, which is not valid for its 2nd argument". Please let me know how I can tell that the second function is also a function of time? Thank you,

Dear all, Is it possible to get a contourplot with NO contourlines? For example, I specified the "filledregions=true" in plot options. contourplot(-5*x/(x^2+y^2+1), x = -3 .. 3, y = -3 .. 3, grid = [15, 15], filledregions = true) But i do not want to show the contour lines inbetween... Thanks again for you help.

I am solving a dynamic problem however due to the complexity of the problem, the software runs out of memory. To avoid the memory los i am tring to write each time step solution into a text file however in order to do that i need to open a file using "fopen"

unfortunately this command enables writing to a file only if followed by "fclose" yet if the program stack before the file is closed the data is lost. on the other hand if i close the file after every time step the new file overrides the old one

 

I had a look at the Maple application "An Interactive Stock Quote Importer"  www.maplesoft.com/applications/view.aspx

which is quite nice :-)  I did not really understand how the author (Samir Khan Maplesoft ) managed to download

yahoo finance data directly inside Maple so I sent him an email asking. He sent me some quite nice code (which I

simply put in a procedure ) that downloads data for any specified ticker symbol from yahoo finance:

 

Hallo!

I have converted a decimal number to hexadecimal, the result in hex is: 18DBD3547552C73BE4DE87731C500.

I think the from Maple converted (decimal to hexadecimal) number ist Big-Endian.

Is there a command in Maple to make this number 16 Byte long (00018DBD3547552C73BE4DE87731C500) and to convert this hex-number to Little-Endian (00C53177E84DBE732C554735BD8D0100)?

Thank's for help.

Is it possible to see the algorithm used by msolve(eqs,2) ? The help page just says

"The procedure msolve has special code for efficiently handling large systems of equations mod 2. "

but I would like to know exactly what it is doing.

I tried print(msolve); and then print(ModularSolver:-Solve); but didn't get anywhere.

How can i plot x-exp(-y^2)=o and sin(5x)/x + 2 − (y − 1)2 = 0.on the same graph maple just repeats whatever input i put in

Is it possible to change the numbers on the dials and gauges to read say $5 $10 etc... or  10% 20% ...?

How about embedding a label directly on the dial?  Like having the actual name of the dial appear within the graphic. 

I want to add some conversion units to the units calculator in Assistants.  Can I do that? 

Specifically I want to add fuel conversions in the assistant.  mpg, L/100km, km/L  etc ...  

Good Afternoon Everyone,

Would any body be kind to see why Maple would not replace the following in the attached differential equation.

Regards,

Moses

I would like to plot the real and imaginary parts of a single complex function, not two different ones.  I understand that choosing the option of "expression_plot" will allow this.  Doing this continues to yield an error.  I would like to see the precise formatting of this command.

 

  Thank you.

Hello.

I am relatively new to MAPLE. I have a large fraction (actually a Bessel differential equation) which I like to break into single terms, i.e. to cancel the denominator with single summands.

"(diff(g(r),r)*f(phi)*r+r^2*diff(diff(g(r),r),r)*f(phi)+g(r)*diff(diff(f(phi),phi),phi)+h^2*g(r)*f(phi)*r^2)/g(r)/f(phi) = 0"

I tried full partial fraction, but it doesn't accept "g(r)*f(phi)" as variable.

any ideas?

all the best.
 

Hi all, i have been using maple for some time now. But one thing still bothers me. The use of radian in stead og degree. I found a way to work around it, but still.

So i looked at the help file, and found some intresting commands like:

• AddSystem - "The AddSystem(unit_name, opts, units) function adds or redefines a system of units in the current session"
• UseSystem

Can't that be used to forcing maple to calculate in degrees rather then radian.
