## Is there a way to make the output of dsolve the sa...

Hello, I am using dsolve to solve a set of coupled differential equations. After they are solved I do some further manipulations on them. Every time I restart maple and execute the document, maple solves the equations but puts them in a different order and has the constants mixed up. Thus I have to keep hitting the (!!!) button until I happen to get the solution I had when I did the further manipulations. Is there a way to proscribe maple's output to a certain order? Here is an example: One time the solution will look like: {F(x) = f(x)*_C1 + g(x)*_C2, G(x) = m(x)*_C3 + v(x)*_C4}

## View Non Zero Range from List?...

I'm using the following bit of code: step1:=1:for w[x] from start by jump to finish do: fsolve(test2,k,complex): answer:=%: k1:=Re(answer[1]): k2:=Im(answer[1]): k3:=Re(answer[2]): k4:=Im(answer[2]): data[step1,1]:=w[x]: data[step1,2]:=k1: data[step1,3]:=k2: data[step1,4]:=k3: data[step1,5]:=k4: step1:=step1+1: end do: Obtain All Data Points from Array points1:=seq([data[d,2],data[d,1]],d=1..nopoints): points2:=seq([data[d,3],data[d,1]],d=1..nopoints): points3:=seq([data[d,4],data[d,1]],d=1..nopoints): points4:=seq([data[d,5],data[d,1]],d=1..nopoints): Obtain Relevant Data Points

## NewMapleGraph...

It's me again, got another problem i have another hyperbolic paraboloid equation 3*x^2-5*y^2=z and it's conic sections at xy(z=0), xz(y=0), and yz(x=0) plane 3x^2-5y^2=0 3x^2-z=0 5y^2+z=0 but i have problems converting those conic equations into parametric equation, so it can be plotted using the spacecurve command Can someone help??

## MapleGraph...

I am stock on this my prof gave me an equation to draw on maple 16x^2=y^2+4z^2 and this is the code i keyed in restart: with(plots): > p1:=implicitplot3d(16*x^2=y^2+4*z^2,x=-100..100,y=-100..100,z=-100..100,numpoints=2000,style=wireframe): > display(p1); and the graph suppose to be a cone rotating around the x-axis but i don't know wut i did wrong, i just couldn't get the graph look like a cone, instead, it looks like a hyperboloid of two sheets, and the sheets are very close to each other Can someone help?? Thx

## How do I compile the OpenMaple example omexample.c...

I am trying to compile the OpenMaple example omexample.c using Bloodshed Dev-C++, but I am getting linker errors. I have tried adding maplec.lib to the linker parameters under project options, and I have also tried copying the library to my working directory and passing it as a compiler command option. Neither has worked. Thanks in advance for your help. Regards, layne

## How use......

When I use: >with(process) >launch("notepad") then notepad is open in the background, but, how do I to run another aplication? with matlab is easy, but e.g. How do I with Origin? or How many formats (i.e. .pdf,.txt, etc.) accept maple? Thanks a lot

## Quadric Surface graph and its trace...

The equation of a sphere is x^2+y^2+z^2=1, and its traces are x^2+y^2=1-k^2 z=k x^2+z^2=1-k^2 y=k y^2+z^2=1-k^2 x=k can somone help me how to graph the traces using spacecurve command so the traces matches the sphere? thx!!

## Numeric D.E. solver help...

Greetings, For a school project i am trying to calculate a trajectory of a spacecraft to mars. Using newtons equations and the numerical D.E. solver i calculated the orbits of earth and mars around the sun(which i am also using as my coordinate origin.) Then i use these results in a differential equation to find the position of a rocket launched from earth. I am shooting it in an arbitrary direction just to get started. The solver does its job and i rename the X,Y,Z coordinates of the rocket (formely called Xr,Yr,Zr) to X3,Y3,Z3. The problem is when i want a numeric answer, i.e i type in X3(400)...i get

## Assigning the output of Minimize to a variable?...

Hi I am using Maple (9.5) to calibrate the value of an expression for a bond to obtain "issue-at-par-value". Part of the procedure is to minimize the valuation-expression by changing the bankruptcy-level. I use the following: B3 := Minimize(HYB(100,10,x,0.06,0.0023),x=0..65); and get typically: [70.003...,[x=50.15...]] When I then need to use these results in the next iteration, I can pick the value (70.003...) by typing V := B3[1]; No problem so far, but I need help to be able to assign the value of 'x' to a variable I can use later. I have studied manuals, Help-pages etc., but as my PhD-thesis is due in shortly, I hope someone may help me..

## Trigonometric Series...

The deflection curve of a prismatic bar can be represented by a trigonometric series (S. Timoshenko, Theory of Elastic Stability, 1st Ed. 1936, p. 23). I am trying to find a way to enter a sine series into Maple of the form: y=a1*sin(Pi*x/l)+a2*sin(2*Pi*x/l)+a3*sin(3*Pi*x/l)+... I have downloaded the FourierTrigSeries package and have not had any success in entering the sine series as defined above. Any suggestions? Thank you for your assistance.

## Maple 11 tutor enter pi...

Hi, New to Maple 11. Using the tutor to solve definite integral. Would like to enter pi/2 as one of the limits. I know control space works in main program, but it does not seem to work while in the tutor. Any help appreciated. Thanks!

## Using Packages...

I have downloaded the FourierTrigSeries package which contains two files: maple.ind and maple.lib. Could someone tell me how to make the routines available in a session? Thank you for the response.
