I didn't see him do 18 or 8 can you share it with me

[@brookeodonnell6850]

thank you so much!! this is my exact homework paper so this rly helped! :)

[@brandonsvideos123]

because question 2 is in the third quadrant, wouldn't the answer be negative (root 2/2)?

[@chiccynugs7164]

In the third quadrant both x and y are negative, so -y/-x = y/x.

So helpful thanks

[@carlosgarcia1468]

for item 2, sin ttheta = -1/root 2 bec sin is negative in the 3rd quadrant.

[@mereiachehade]

Why isn't #2 negative?

[@leeoliver391]

It is!! You are correct! Because anything beyond 180 degrees on the unit circle goes into the negative region of the y axis :-)
