MaplePrimes Questions

Hello there im trying to find the value for x(solve) in an equation, how do i do that in maple?? For example...2x-a/x+a - x+3a/a-x = a^2/a^2-x^2 + 3 Thanks
I am having some trouble figuring out exactly how to organize data points to be used with the Data Analysis Assistant in Worksheet Mode. I initially extracted the expression sequence of data points from the data structure generated by the plot command (an ordinary 2D plot of a function); I then put the expression sequence in a list and put that in a Vector, and was successfully able to look at the data with the Assistant. I'd like to use my own data points (i.e., from Physics labs, etc.), but I don't know what type of data structure to use. The Assistant tells me to put them in either a Vector or an Array, and I've tried both; I get an error indicating that the order (or dimension) of the Curves structure cannot be found (or something to that effect).
Hi, Is there any method to find an integral over a line on the upper-plane of x, from –infinity+I*0 to +infinity+I*0 by the form Int(exp(-I*(x-1/x)*theta) /sinh(x-1/x),x=–infinity+I*0.. +infinity+I*0) Or more complicated Int((x^2+x+1)/sinh(x-1/x)*exp(-I*(x-1/x)*theta),x=–infinity+I*0.. +infinity+I*0) Where theta is a constant real number. Cheers Sayed
I know using partial_diff can do Grad of a rank 1 tensor (i.e. vector) and get a rank 2 tensor. How do I do the reverse? is there any simple way? Thanks
I would like some help on how to include mathml formulas from Maple in jsp pages for Maplenet. I use de MathML:-ExportPresentation to obtain the mathml form from Maple, but I cannot see it correctly in a jsp page. It seems mathml works fine when I have a html page. I would like to know if is there anything else I should do so that i can work in jsp too. Thanks
I have learned in Brownstone site how to create,
using latex, sketch questions for Maple TA.
I could create a question bank, formed by sketch mode questions,
and then uploaded it to Maple TA, but the applets just don't work.
There are no java error messages.
On the java console i get messages like:

Could not add node because of conflicting x-coordinate:
node with matching x-value already present in system
Please select another point.
Hi, I'm very new to Maple. I have a set of equations. 16 equations with 16 unknowns, so it is possible to solve for 16 unknowns. I can solve using matrix if all of these equations are linear using my calculator; however, 2 out of the 16 equations are non-linear (x^2...ect) equations. I would like to use a software to solve for it. Is there a way to solve these 16 equations using Maple? If there is, please show me how, the more details the better for me because I'm very new to Maple and not very familiar with using Maple user interface. Thanks
Hello there.... I recently purchased maple10-student edition. I am having trouble trying to use it effectively! I am trying to type in simple maths questions into Maple,but Maple does not seem to recognise it? Ive tried hoping ill be able to get some help with regards to my questions? My question- im tryind to find the fraction equivalent to the fraction ab/cx ? How do you type that in and get the answer? The same goes with this fraction that im trying to simplify a/b + b/a - c/d = How do i type that in ? And can maple give explanations towards its answers?
How do I make odeplot scale the Y axis from 0?

For reasons I do not understand it has started to scale from the minimum value.

My current expression is

odeplot(dsol,[sSX_(u),sSY_(u)],0..(0.9), title = "Postion",
legend=[position],axes=FRAME,scaling=constrained );

Thank you in advance
Hello, I am trying to call a matlab function from maple and get the following error msg: Error, (in OpenEngine) Maple/Matlab Link: Can't start Matlab engine I have tried the with(Maple) command and it shows shows a list of functions indicating that the two packages are linked. I would highly appreciate if someone could help me out with this. Thanks Saqib
Good morning.
I'd like to know if (and how) it is possible to use Dirac's bra-kets notation, so often used in Quantum Mechanics and Physics courses...
I searched in this site and with google, but I found no hints...
Probably that notation conflicts with the methods used to write a vector, e.g v:=; , but I wonder if it exists a workaround, an hack, a package, a library or something else to accomplish the task...

Thank you.
Have a nice day!

I'm looking for a C library that does symbolic manipulation - particularly integration. Does anything like this exist?
We use maple to generate all of our computational bits, dump this out to header files, and include this in our code base. A lot of the code that is generated is redundant so it would be nice to have codegen[C] know, or at least be able to be told, to optimize the entire code being dumped to the same header file. Is this possible? Examples follow... " ..... DCb := array(1..3): lp:='lp':ip:='ip':m:='m':ap:='ap':jp:='jp':a:='a':l:='l':j:='j':i:='i':k:='k':kp:='kp': for ip from 1 to 3 do DCb[ip] := sum(sum(sum(sum(sum(gd[ip,jp]*gu[ap,lp]*jacu[m,lp]*jacu[a,ap]*dJ[jp,m,a],m=1..3),jp=1..3),lp=1..3),ap=1..3),a=1..3):
Ok I am new to Maple and can't seem to get anything right with it. I am taking trigonometry online (big mistake) is killing me. I need help with problems like this: Find all solutions of the equation 2 sin(2x)=sqrt(3) in the interval [0,2π]. Can any one help?
How do I animate a sinus function between 0 and PI along an axis to simulate a travelling wave? I would greatly appreciate any help.
