*Do

Answer 4

I know my unit circle I'm just having trouble remembering what to do when you are using tan. I know it would be -sqrt(2)/-sqrt(2) over -sqrt(2)/-sqrt(2) but how do simplify that or is tan totally different

Answer 5

\(\frac{b}{b}=1\) and \(\frac{b}{-b}=-1\) it is one or the other

Answer 6

you are in quadrant 3, both sine and cosine are negative, so it is 1

Answer 7
