## solving a set of linear and non-linear equations...

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

## Maple 10 student...

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 everything......im 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?

## ?Make odeplot scale Y axis from 0?...

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 );

## Calling matlab from maple...

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

## Dirac's bra-kets notation...

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!

## Seeking C Library for symbolic manipulation...

I'm looking for a C library that does symbolic manipulation - particularly integration. Does anything like this exist?
Thanks,

## ... use codegen without redundency in the code out...

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):

## Trigonometry help...

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?

## wave animation...

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.

## Single line output...

Hi all, I'm sure this is very simple - but I simply can't figure out how to do it - and I can't find any information on it. I have an equation which has been integrated and that's all wondering. However, I would like the equation to be outputted on a single line so I can copy from one window and paste it into another. As it stands Maple displays the equation over several lines so I can't do this. I could of course retype it - but its rather complex and I'd rather have the equation that Maple outputs so I know there isn't a mistake I've introduced. For what I can tell this is Maple's 2d maths display, which is default. I can see how to change it in a gui version of Maple, however, I don't have access to a gui version - its command line on linux... Its Maple 10 as well if that helps at all.

## How do I convert rational powers to floating point...

Hi folks, I'm using the IntegralTools(Change) function to change the variables of integration in a double integral to lower the order of a polynomial under a radical prior to integration (praise to Axel!). The result contains exponents under the radical and in the limits of integration that seem to defy Maple's numerical integration routines. (Sorry for not using HTML! I tried to present in 2D math, but the preview post omitted the math entirely. Just paste it into a worksheet to convert this text mess into a mathematical one.) `Int(70871722182849/100000000000000000*Int((20.6066600725-0.164853280580e-1*sqrt(1.562500*(RealDomain[`^`])(10, 6)+7.58249999999*(RealDomain[`^`])(10, 6)*(RealDomain[`^`])(xi, 99999999999999939/100000000000000000)-3.35631780000*(RealDomain[`^`])(10, 7)*(RealDomain[`^`])(xi, .10000000000000)*(RealDomain[`^`])(xi, 99999999999999939/100000000000000000)+9.19908900000*(RealDomain[`^`])(10, 6)*(RealDomain[`^`])(xi, .20000000000000)+9.19908899998*(RealDomain[`^`])(10, 6)*(RealDomain[`^`])(xi, 99999999999999939/50000000000000000)+7.58250000000*(RealDomain[`^`])(10, 6)*(RealDomain[`^`])(xi, .10000000000000))+50.0000000000*(RealDomain[`^`])(xi, .10000000000000)+50.0000000000*(RealDomain[`^`])(xi, 99999999999999939/100000000000000000))*(RealDomain[`^`])(xi, 0.70163004961021e-1), xi = (RealDomain[`^`])(c, 1000) ..
