(%i3) x;

TIA,
try
x:trigsimp(sin(a)^2+cos(a)^2);

Thanks,
in the meantime I've found also
trigrat(x);

Hello,
How can I tell maxima that sin^2 + cos^2 = 1 ?
For example:
/******************************/
(%i2) x: cos(a)^2+sin(a)^2;
2 2
(%o2) sin (a) + cos (a)
(%i3) x;
/******************************/
and I want to see here 1.
