If is real and . Then triangle with vertices 0, z1 and z2 is
Thus, triangle with vertices 0, z1, and z2 are vertices of an isosceles triangle.
If is an imaginary cube root of unity, than value of the expression.
an ellipse, then a lies in
Reflection of the line in the real axis is
If A(z1), B(z2) and C(z3) are the vertices of a triangle such that
then area of the triangle whose vertices are z1, z2, z3 is
