Good day everyone,

I am running a maple code for a pde and is given the error code "Error, (in pdsolve/numeric/process_IBCs) initial/boundary condition must be given in terms of the dependent variables of the problem only ([W]), got ((D@@2)[1](W))(0, tau) = 0". The link is attached below.

Thanks in advance.

Good day everyone,

I am having a problem writing a PDE code and it is given an error code

"Error, (in pdsolve/numeric) initial/boundary conditions must be defined at one or two points for each independent variable"

The link is attached below. Please, help. Thanks

Good day sirs, 

I have a code given the error code "Warning, solving for expressions other than names or functions is not recommended".

Please, anyone with useful information. 

Thank you in anticipation for the your response.

The Maple file is attached below.

Good day everyone,

I have problem-solving this system of equations using Iterative Projection Theorem. Anyone with a better explanations please.

The equation is as stated below. 


Solve this set of equations using the iterative projection theorem.

(x1 - 2)2 + (2x22 - 6)2 - 5 = 0

(x12 - 4)2 + (x2 - 10)2 - 39 = 0

Take the provisional values of  x1 and x2 as x01 = 5, x02 = 4, 

Thank you in anticipation

Good day everyone,

I am trying to write various parameters for two functions using "if loop" but it is substituting for the first one only. Anyone with useful information, please.
