∴z 1,z2,(z 1+z2)？ The modes are equal in length and the divergence angle is 60.

Z 1, z2, (z 1+z2) form an equilateral triangle.

∫z 1+z2 = 2i

∴? z 1，z2？ The real part of is opposite and the imaginary part is equal.

z 1，z2？ The principal values of radial angles are 30 and150 respectively.

Imaginary part of z65438+0 = imaginary part of z2 = 2i/2 = i.

The real part of z 1 =-z2? = cot30 = = real part of√ 3

So what? z 1，z2？ What are they? √3+i and -√3+i
