My friends

int(simplify(f, symbolic), r)

works for me, THANKS a lot!

But it is strange for me that such a powerfull computing software could not solve this integral in a direct way! Maybe Integrating has some tricks in Maple that I do not know, similar this trick that you used for solving the integral here.

Dear Robert

Thanks very much. Honestly I am not a professional in Maple like you, so I do not know what is Groebner basis. I am a theoretical physicist and my question is whether these equations have an answer or not. I mean x,y and z. I prefer the answer do not be unique. k is not a parameter of my work, I defined it for simplicity of expression. I hope these equations have answers and I will be lucky if my primary equations be dependent. It mean I need some freedom in choosing final answer.

Would you please help me?

Regards

Vahid

Dear Axel Vogt

Thank you for answer. Would you please tell me what was my mistakes? Why when I substituted the results in original equations did not arrive at zero?

As you can see in the below attached file, x and y have 2 answer. But you told that y must have 3 ones. Why x has 2 answer?!

So Can I be confident that these results are true? I mean x,y and z are answers of the equations? It seems the equations are not independent, because we have no expression for z.
