How do I enter a complex number in polar form? |

##### How do I convert a rectangular complex number to polar form?

If the complex number is stored in the variable

`A`

(for example), use`[abs(A),angle(A)*(180/pi)]`

to find the magnitude and angle in degrees

##### How do I enter a complex number in polar form?

I like to use the closely related exponential form for this one. if the polar number is

`A∠Θ`

, I enter`A*exp(j*Θ*(pi/180))`
