Question

Let ${{z}_{1}}=3+2\mathbf{i}$, ${{z}_{2}}=2-5\mathbf{i}$ be two complex numbers. Express ${{z}_{1}}$ and ${{z}_{2}}$ on the Argand diagram. Hence, using the same Argand diagram, ${{z}_{1}}^*$, ${{z}_{1}}+{{z}_{2}}$, $\mathbf{i}{{z}_{2}}$.

Accepted Answer

(a) $z_1:(3,2),\ z_2:(2,-5)$ (b)(i) $z_1^*:(3,-2)$ (b)(ii) $z_1+z_2:(5,-3)$ (b)(iii) $iz_2:(5,2)$
