Hi,

 

I was reading the manual for Maple 13 and playing with some commands.

There is an equation: sin(x)=cos(x) and you can solve it by the solve command.

If you want all solutions, you just put there AllSolutions attribute and you get

 

(1/4)*Pi+Pi*_Z1~

 

I wonder why there is a tilde (~) behind "_Z1", because each integer satisfies

the equation (there is no need for an assumption).

 

I tried to use RealDomain package as well. But then the "AllSolutions case"

returns no solution. Why is this happening? It is not supported for RealDomain?

 

Thanks for every suggestion,

Jarek
