I want to solve this system of PDEs. Please let me know how I can solve it.

Kindly find both my code written in Maple and the image of the problem.



Is there anyone able to solve this integral for me?


Hi all, 


How could I be certain about the correctness of these answers? I am sure that the variation of the parameter, C1, must be monotonic; just in one dircetion... increasing or decreasing. As you could see from the last result in the first command, the data are false... However, by the second method, the answer is different from that of the first!!!? Both of them are derived by 'fsolve'
In the third way, the command dsolve, produced an array of resutls, C1 and Nu, and there is just one correct solution... It is confusing.

Hi all,

I don't know why this file doesn't work anymore! It was ok last week. I even reinstall the Maple on my laptop, but it went wrong again...


Please help me.

Hi all,

Please help me to get a solution for all the desired data in the attached file. As you could see through it, just for 4 out of 20 desired Br, there are answers by the command:
Notice that If I write Br= -7.0 there is no solution, but I wrote Br= -6.999999, and the solution was achieved simply; just by applying an approximation value for '7'.

I don't know why for other data there are no solution...
