Hi I wanted to simplify my equations so that they include i. this is my equation: w*(2*d*(d^2 - 1)^(1/2) - 2*d^2 + 1)^(1/2). I would like to make it become w*(1-d^2)+i*d*w. is there any way this is possible?

No, because the equivalence you show is only true if
w = 0 (with any d)
or
d = 0 or 1 (with any w)
