# How do you write the complex number 3 in polar form?

Nov 28, 2016

$\left(3 , 0\right)$

#### Explanation:

3 is positioned 3 units to the right of the origin on the x-axis. Thus the angle between it and the x-axis is 0.

To >convert from $\textcolor{b l u e}{\text{complex to polar form}}$

That is $\left(x , y\right) \to \left(r , \theta\right)$

Here r = 3 and $\theta = 0$

$\Rightarrow \left(3 , 0\right) \to \left(3 , 0\right) \leftarrow \text{ polar form}$
