Question

Find all polar coordinates of point p where p = (6, -pi/5)

Answer 1

Given a point in coordinates form
`(r,\theta)`, one can compute the cartesian form like this:

`(r\cos\theta,r\sin\theta )`
We have:

`r=6,\theta=-(\pi)/(5)`
We get the cartesian form then:

`\left(6\cos-(\pi)/(5),6\sin-(\pi)/(5)\right)`
