I have a question about extracting the real part of a complex expression.
for simple ones like 2+3i, it is a easy case. for even more complicated ones like (2+3i)^(1/2), I can use complexExpand and then try to get the numeric results.
My questions is, how about symbolic expressions? say, Re[(w*t*i+a*t*D)^(1/2)], here w, t, a, D are all real numbers. The mathematica seems that could do nothing about this.
Anyone could help me?
