Question

How do you graph `r=-4theta`?

Answer 1

Table for making the graph of the spiral, with unit of `theta` as
`(180/pi)^o=57.3^o`, nearly:
`(r, theta): (0, .0) (4, -1) (8, -2) (12, -3) (16, -4) (20, -5) ...`

Explanation:

Here, `r=-4 theta >= 0` So, `theta<= 0`.

Let us keep the sense of rotation, for `theta in (0, -oo)`

Table for making the graph of the spiral, with `theta` in radian = #

(180/pi)^o=57.3^o#, nearly:

(r theta): (0, .0) (4, -1) (8, -2) (12, -3) (16, -4) (20, -5) ...#
