 s=solve(sin(x)^2 + cos(x)^2 == 1)
 s =
   C_

C_ is the set of complex numbers. That looks right, since the identity is true for any value of x.

How did you know about C_? Where can I get this information?

Note that in my answer, C_ is a link to the documentation. I found it by Googling "matlab symbolic toolbox C_".
