A regular hexagon has vertices at $1-i, 0, a, b, c, d$ clockwise in that order, as in the picture below:
Then what is \(\operatorname{Im}(a)\)?
+532 if you tell me what Im(a) means(does it mean imaginary part?), i can solve it, but i can tell you the coordinates.
convert to the real plane, so distance from a to origin is sqrt2/2. now since the angle made by a, origin, and y axis is 15 degrees, you use the fact that cos 15 = (sqrt6+sqrt2)/4, and the fact that sin 15 = (sqrt6-sqrt2)/4, so then the coordinates of a would be ((sqrt6-sqrt2)/8, (sqrt6+sqrt2)/8).
assuming it means imaginary part, answer is (sqrt6+sqrt2)/8.
