Hi,
it is possible, just try
var('x')
((cos(x)-sin(x))^2).trig_simplify()
which will result in
-2*cos(x)*sin(x) + 1

Hi,
it is possible, just try
var('x')
((cos(x)-sin(x))^2).trig_simplify()
which will result in
-2*cos(x)*sin(x) + 1
since sin(x)^2+cos(x)^2=1 (I think you mean this formula with the trigonometric identity).
