I have a set E of linear equations in variables x[1],...,x[8] (which I created with X := Matrix(8,1,symbol=x)). I now call

 

> solve(E);

I get back something like

 

x[1] = x[2]-x[3], x[2] = x[2], x[3] = 5, ...

 

I would rather like to get

 

x[1] = t[1] - 5, x[2] = t[1], x[3] = 5, ...

 

back.

 

How to do this? I do want to use the solve function (not LinearSolve et.c.).

I'm supposed to do the following. I tried to ask my teacher how I could go about doing it and she told me to just figure it out. I am supposed to find the linear and quadratic approximations to the function f at x=a. Then, I'm supposed to sketch the graph of the function and its lienar and quadratic approximations.

The linear approximation is:

P₁(x)= f(a) + fprime(a)*(x-a)

The quadratic approximation is:

P₂(x)= f(a) + fprime(a...

I have that problem that I am trying to solve the following equation explicit:

TY = RootOf(6.750969101*10^26*_Z*1000^(9/59)*800^(41/59)-1.015701668*10^27*1000^(50/59)-1.189275761*10^27*800^(50/59)+1.103397224*10^26*_Z*1000^(32/59)*800^(18/59)-7.457053114*10^23*3^(1/5)*1000^(41/59)*800^(50/59)*_Z^(4/5)*sqrt(12500)*4^(19/20)*(800^(9/59)+1000^(9/59))^(1/50)*(702.222720*1000^(9/59)+976.508160*800^(9/59))^(4/5)-7.457053114*10^23*3^(1/5)*1000^(50/59)*800^(41/59)*_Z^(4/5)*sqrt(12500...

Can maple in any way simplify this any further?

-(1/4)*m*omega*sin((1/2)*omega*T)*(2*cos((1/2)*omega*T)^2*xa^2+2*cos((1/2)*omega*T)^2*xb^2-xa^2-2*xa*xb-xb^2)/((cos((1/2)*omega*T)^2-1)*cos((1/2)*omega*T))

I've tried simplify, radnormal, combine but am wondering why maple does not convert for example the denominator in sin(omega*T) 

How do enter and use the notation of a step function (u(t-3)-u(t-4) in maple to use in calculations? thanks

Hi,

I wondered if you would be able to help.

I've set up a for-loop and while-loop that substitutes values of j and k into a given function

I want to get the answer for every right for example right[1], right[2]..but this code give the answer for right[1]nd right[6] only..

 

 P := array([[1, 4], [2, 3], [3, 2], [4, 1], [6, 5], [6, 1], [6, 2], [5, 3]]);

j := 1; k := j+2; Fold := 0; Fnew := 1; counter := 0;

I think Maple is missing some lines and significant points. Here I leave another contribution to the possible implementation of a new algorithm to draw the circle of Taylor.

Hi, how I can find the variable Z in this equation? thanks.

I know how to export to .png or .jpg but I'm not quite pleased with the quality of the images.

Is there a way to export high quality images? i.e. no sharp edges of the function in the plot

I have define the following ODE system

restart;
with(LinearAlgebra);
dC1 := diff(C1(t), t) = -2*a1*C1(t)+b1*C2(t);
dC2 := diff(C2(t), t) = 2*a1*C1(t)-(b1+a1)*C2(t)+2*b1*C3(t);
dC3 := diff(C3(t), t) = a1*C2(t)-(2*b1+a2)*C2(t)+b2*O1(t);
dO1 := diff(O1(t), t) = a2*C3(t)-b2*O1(t);
syst := dC1, dC2, dC3, dO1;ics := C1(0) = 1, C2(0) = 0, C3(0) = 0, O1(0) = 0;
func := {C1(t), C2(t), C3(t), O1(t)};
sol := dsolve([syst, ics], func);

After evaluating...

I cannot access HELP ?orbital in the Orbital Package; it does not appear in "Science and Engineering/Orbitals" . I have followed Initialization instructions in orbitals.mw, creating "c:\MapleLibs" in Windows8 . Is libname:=libname,"c:/MapleLibs" correct? Any help on this help would be a help.With thanks,Michael Caola

Good afternoon Sir.

 

I request you to help me out in writing Maple procedures to execute, Numerical methods such as

1. Bisection ethod
2. False position method
3. Fixed point iteration
4. Newto-Raphson method
5. Generalized Newton's method
6. Mullers method
7. Graffe's method.

 

With thanks & regards

My attempt:

RealDomain[solve]({x^2+y^2+z^2 = 3, x+y+z = 3}, {x,y,z});

             {x = -RootOf(_Z^2+(z-3)*_Z+z^2-3*z+3)-z+3, y = RootOf(_Z^2+(z-3)*_Z+z^2-3*z+3), z = z}

 

In fact, the system in the real domain has a unique solution x = 1, y = 1, z = 1. It is easy to find by hand, noting that the plane  x + y + z = 3  is tangent to the sphere  

Running Maple 14. When I try to "export" a worksheet to latex I receive "Unable to export expression to LaTeX. Ensure that the Adobe Font metric filesare located in Maple's AFM subdirectory"where can I find those font metric files? An internet search gives very complex pages full of information about fonts etc. Is there some simple way to do this? thanks, Greg.

Prior to the Finance package being updated to include holidays there was no easy way to have Maple generate when holidays occurred.  Hence for newer Maple users there would be no need for such a thing but I had an interest to create one for earlier versions.  The idea is quite simple enough and this is one solution I came up with.
