Question

Converting regular coordinates to polar coordinates?

Answer 1

(6, −6)

Answer 2

I got 6sqrt(2) for r

Answer 3

But I can't solve for theta

Answer 4

thats correct

Answer 5

theta = tan inverse (y/x)

Answer 6

tan inverse (-6/6) = ...?

Answer 7

-45pi/180?

Answer 8

which angle gives tan theta as -1?

Answer 9

yes, in radians, its -pi/4
in degrees -45

Answer 10

if you need a positive angle, just add 180 degrees (or pi radians) to it, because tan function is periodic in pi

Answer 11

none of those are working :( i tried -pi/4 and 3pi/4

Answer 12

it wants it in radians

Answer 13

-pi/4 should work

Answer 14

0 ≤ θ ≤ 2π

Answer 15

ohh, then 3pi/4 should work

Answer 16

wait, try
7pi/4

Answer 17

That works!

Answer 18

Thank you so much!

Answer 19

welcome ^_^
