    Hello Everyone.

   

   sin(x) - x + (x^-1i)^1i , solve fully ?

       Best Regards.

By ordinary rules sin(0)=0 and (x^-i)^i=x^1=x. I guess that's why Mathcad 11 (Maple) gives this answer:

Success!

   Hello Everyone again.

       The question : sin(x)  +  e^(pi/2)  +  x  -  (x^-1i)^1i  solve, fully ?

              Best Regards.
