Question

How do I express -3+4j and -3-4j in complex polar form, using radian measure?

Answer 1

For exact radfian measure you could put the value of `pi, theta and alpha`

Explanation:

Multiply and divide by `5` we get `5(-3/5+4/5j)`
In polar form we get `5(cosalpha+sinalpha j)`
Where absolute `tanalpha=|-4/3|or alpha=pi-tan^-1(4/3)` as `alpha` lies in second quadrant

Similarly `-3-4j` would be `5(costheta+sintheta j)` where
`tantheta=|4/3| or theta= tan^-1(4/3)-pi` as `theta` lies in 3rd quandrant.
