Why the interface typesettings option doesn't affect the content of a MathContainer?

I opened a new document. Then I inserted the command interface(typesetting=extended); to improve the visualization of a disequation's solution. It works in the worksheet, but it doesn't work in the content of a MathContainer.

Hello! I have written a algorithm. Can you help me find errors? thank you very much. sorry, my English is not very good!

LL:=proc(A::Matrix)
uses LA= LinearAlgebra;
local i, j, k, n:= LA:-RowDimension(A),
L:= Matrix(LA:-Dimensions(A));
L[1,1]:=sqrt(A[1,1]);
for j from 2 to n do
L[j,1]:=(A[j,1])/(L[1,1]);
end do;
for i from 2 to n-1 do
L[i,i]:=(A[i,i]-add(L[i,k]^(2),k=1..i-1))^(1/(2));
for j from i+1 to n do
L[j,i]:=(1/L[i,i])*(A[j,i]-add(L[j,k]*L[i,k],k=1..i-1));
end do;
end do;
L[n,n]:=(A[n,n]-add((L[n,k])^(2),k=1..n-1)^(1/(2));
L;

I want to know the mistakes i have made in the documents attached to get the expected results every time.

I have been using MapleSoft since 2013 to solve mathematical problem. However, I could not solve the following set of differential equations.  Would you please, solve the problem and return the file how you solve it? Thanks in advance.

Is it possible to make a call to any of the plot options without using it's designated name?

I don't know if I'm clear enough but for example

Instead of
plot({x^2,x+1},linestyle=[dash,dashdot])

use some argument that designates the first and second option etc ...
for example like
plot({x^2,x+1},linestyle=["%1","%2"])

Hello,

 I am trying to solve an differential equation in Maple, but I have no response from Maple.Can someone give a look for me? The coefficients a and b cannot be zero.

 Thanks a lot.

Hello,

I'm having some issues with this procedure it seems to take a very long time to evaluate. There is also an error in the Histogram I can't seem to fix... Does anybody know why? Any help would be greatly appreciated! Thank you in advance!

Kind regards,

Hello everybody

I have a system of ODEs that are too large. I am trying to solve this system using Maple. The corrsponding file has been uploaded. I have 2 question. 1- Does anyone know what is the source of error? 2- Is this a high expectation for Maple to solve such a too big system of ODEs. Note: It makes a few minutes to run all the programm.

Thanks in advance

Hello

i have an ODE like this:

I sove this ODE with plot order:

with(plots);
odeplot(sol, [x, (3*D1*a+4*D2)*P(x)/((1-q*S(x))*D2)], .5 .. (1/2)*Pi, tickmarks = [[seq((1/10)*i*Pi = (180*i*(1/10))*`°`, i = 1 .. 8)], default]);
my plot work very well. but i need to plot this ODE with five different parameter (q for for instance, q=0.1 & q=0.2 ....) all in one axis. something like this:

Hello,

I try make 2 calculation with one commant. So there should be two seperate answers in the last line. Who can help me? So the last line should be 2.387 and 0.

restart;
restart;
st := time():
ifactor(49! + 1);
(1021) (3119969417) (7374967) (139935066631148413819385559764102\

  5027693) (18503)
time() -st;
                             2.387
restart;
st := time():
isprime(49! + 1);
                             false
time() -st;
                               0.

I have some problems about plotting in Maple.

Question1. I have tried to plot this function for different intervals, but there is no resulting graph.

plot(1+18*(sinh(9*x-9)-sinh(3*x-477))^2/(9*cosh(9*x-9)+cosh(3*x-477))^2,x=-4..4);

What do you think why this happens?

Question2. plot(1+18*(sinh(9*x-9/2)-sinh(3*x-477/2))^2/(9*cosh(9*x-9/2)+cosh(3*x-477/2))^2,x=-1..1);

The graph of this function is a wierd one. Is there any problem?

Hello, 

I am trying to get W(x,y,y')=y*y'/x

I am trying 

omega:=(x, y(x), (diff(y(x),x)))-> (y(x)*(diff(y(x), x))/x);

but get 

Error, invalid parameter; functional operators require their parameters to be of type symbol or (symbol::type)

Can anyone help me out?

thank you

In this code, plot() and Norm() fail when used over a piecewise() function:

Error, invalid input: VectorCalculus:-Norm expects its 1st argument, v, to be of type {Matrix, Vector}, but received piecewise(t < 0, Vector[row](2, {(1) = -1, (2) = 0}, attributes = [coords = cartesian]), Vector[row](2, {(1) = 1, (2) = 0}, attributes = [coords = cartesian]))

Note that the same Norm() and piecewise() work fine when used without the plot() function:

Norm(vec(1));
                               1

Code works fine when piecewise() is removed, leaving a plot() / Norm() combination, for example:

So only the simultaneous combination plot() / Norm() / piecewise() fails. 

Finally, the question is:

Is there a way to plot Norm() / piecewise() combinations without workarounds like intermediate PLOT structures?

Thank you

hello

I have an ODE plot like this and I want its horizontal axes to be in degree instead of radian, but I don't know how
