In this problem the boundary condition is

Note: F=g in our problem.

eta approaches N.

Thank you.

Hello, I need to figure out what theta is through this matrix:

Should I use a solve command for this?

I need to find all integer solutions of these multivariable equations (and many more similar equations)

I have the boundary conditions that b-1 ≥ a1 > a2 ≥ 0

How can I do this in Maple?

For context, b is a base and a1 and a2 are digits in a b-adic number where a1 is bigger than a2. Solutions to these equations correspond to numbers that have a particular property.

I have posted this question on math.stackexchange, but saught an algebraic approach rather than a computational one. Here it is shown that a1 and a2 are linear functions of b. This is where the families of solutions come in. Mathloves answer is detailed and potentially useful in regards to formatting the answer.

Thank you for any help / advice. Ben

I have to use the Chinese Remainder Theorem but once I have found m^e I cant seem to figure out a way that works to get just the message without the exponent. I assumed that the exponent is 3 since the message was encrypted 3 different times. How can I do this with Maple?

convert(...,Int) in Maple 2018.2 works for fourier, invfourier, laplace, but does not work for invlaplace.  

Why is that? Is there a workaround?

expr:=fourier(f(x), x, w):
convert(expr,Int);

expr:=invfourier(f(w), w, x):
convert(expr,Int);

expr:=laplace(f(s),s,t):
convert(expr,Int)

expr:=invlaplace(f(s),s,t):
convert(expr,Int)

Was expecting to see the Mellin's inverse formula.

Ok so when a module is loaded, there is a .dll file that loads a list of symbols into maple.exe, what can be done if an error occurs for which the debugging output declares that the PDB file for the module could not be found? 

I have read that the program database file stores debugging information related to the locating symbols, how can i fix this if my computer isn't finding theres files for a list of .dll it attempts to load into maple.exe, or is there a way for which i can make these files for each corresponding module?

It seems that the forum activity of the user  Markiyan Hirnyk   is no longer accessible.
Is it a site problem?

how I can pdsolve these equations?

I have multiple accounts. I would like to delete them. Please tell me how to delete it. Thank you.

I'm using the differential operator D to differentiate variables and look at the structure of the equations, i.e. turn things like

D[1]u-vt+v^2=0 into

D[1,2](u)-D[2](v)*t+v*D[1](t)+2*v*D[2](v)=0

However, it is assumed that this is a commutative operator, i.e. D[1,2]=D[2,1]. Can I use an option to have it not commute, or should I look into using the DETools package?

Thanks,

Mike

How can I calculate the Euler-Lagrange equation from the Lagrangian density from Gauged Baby Skyrme model in maple using the physics package? Here, the rules of the operation in the inner space are the same that of the vectors conventional: dot and cross products, etc...
Following below the Lagrangian density.
