tan 5pi/4
Welcome to openstudy :)
D you know your unit circle/triangles?
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
oh okay I get it! what would I do if the values weren't the same?
