I recieved the following error:

Error, (in ifactor/QuadraticSieve:-SieveCube) sieving failure

But when I review the procedure ifactor, it doesnt tell me anything about A Quadratic Sieve algorithm, and it's really long and looks dodgey and suspicious, like line 24 for example, why is it computing the greatest integer divisor of a local variable and a random enormous square free number? and then another with an additional factor a few lines later? 

I need the final line of the uploaded worksheet to be the "Select Action", preprogrammed prior to the execution of the insert xml command, how do i do this?

Hi,

How can I extract the coefficients of u_ij in Eq.(3) to form a system of PDEs in F, P and Q?

Hi

I use Maple 2016.

The following command calculates semicircle perimeter, but it returns infinity.

`assuming`([int(sqrt(1+(diff(sqrt(R^2-(x-R)^2), x))^2), x = 0 .. 2*R)], [R > 0])

I was trying to learn more about the commands in this package and found it to be someone non satisfying:

Maple gave Lie algebras of a system of PDE in which some of them do not leave the system invariant. Dont know whether the mistake is maple's or mine. File attached.

restart:
with(PDEtools);
PDE :=  diff(y(x,t), t)-diff(y(x,t), x,x,t)-diff(y(x,t), x$2)+ diff(y(x,t), x)+y(x,t)*diff(y(x,t),x)=exp(-t)*(cos(x)-sin(x)+1/2*exp(-t)*sin(2*x));

# Initial/boundary conditions 
  BCs:=y(0,t) = 0, y(Pi,t)=0;
  ICs:=y(x,0) =sin(x) ;

pdsolve(PDE, {BCs,ICs});
exact_solution:=exp(-t)*sin(x);
Test1:=pdetest(exact_solution,[PDE, BCs,ICs]); 

The solution of the PDE is exp(-t)*sin(x).

I want to check whether it is right or not by Maple. 

I wrote the code. You can download the code.mw  

But, the code doesn' t work. What is the problem?

Thanks.

The worksheet below animates a hamster running back and forth on a linear floor within a wheel. Its motion is such that the wheel remains stationary.

What math would describe the hamster running back and forth such that the wheel oscillates with a constant frequency and the floor's vertical angle oscillates between plus and minus an angle greater than zero and less than 2 Pi?

I am trying to solve a simple two-equation linear system with solve, but I keep getting this weird result where the magnitude order of the numerator and denominator don't cancel out. Whenever I have a linear system with floating-point numbers, more unknowns than equations and try to solve it for a specific set of variables, this happens.

Any suggestions on how to get around this? Or do I need to solve it manually?

Can you help me

myproc := proc () local img1, img2, img3;

with(DocumentTools); with(DocumentTools:-Layout);

img1 := "c:\\1.jpg"; img2 := "c:\\2.jpg"; img3 := "c:\\3.jpg";

print("Title 1 row 1, picture 1"); print(img1); print("Title 2 row 2, picture 2");

print(img2); print("Title 3 row 3, picture 3"); print(img3);

print("The End");

end proc

Hello,

I am trying to solve a set of coupled ODEs in the following code (ODE_Prob.mw). But I am getting an error.

Please, what does this error mean and what is the solution.

Thanks in advance.
