Greetings!

I'm triying to solve this system in Maple:

  beta = cot(beta),

  0 < beta < (1/2)*Pi

But when I execute this statement

  p := solve({beta = cot(beta), beta>0, beta<(1/2)*Pi}, {beta})

the value of p in NULL.  Maple doesn't show any errors. 

Edit: Example from the "solve" help article works as shown, that was my typo.

Could you please tell me, what am I doing wrong?
