Hi,

I have to solve a very complex trigonometric equation which has 0,1 or 2 solutions between 0 and Pi (it depends from some parameters...).

The first problem I solved is to find the two solutions (when they exist), because at the beginning, the fsolve function returned only one solution. So, reading in your site, I solved this problem "splitting" che solutions domain in two parts in which I expect to find the two different solutions.

So for example a I wrote:

Hi everybody,

I have just started to learn using maple and now I have a trouble.

I thought programming was similar to C language, and I tried to write this simple code:

   b := 5;

   if a = b then 

        print('before'); 

        plot(x^2, x = -2 .. 2); 

        print('later')

   end if;
