Answer 4

that's not correct @CrazyTurtle483

you have half of it right

Answer 5

keep in mind that you need to add on pi to make the angle do a half-turn

Answer 6

Well would it be option 4 then since it's 1 and -1?

Answer 7

yes it's D because (2n+1)pi = 2n*pi + pi

the +pi at the end gets that half-turn

Answer 8

so you would normally face the direction of -pi/6, but then do a half turn, and then walk backwards 1 unit

Answer 9

Ok that makes more sense then

Answer 10

I didn't know it would change like that
