    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

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

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