Best ResponseYou've already chosen the best response.0your job is to find a number (angle ) in the interval \[[\frac{\pi}{2},\frac{\pi}{2}]\] whose tangent is \[\frac{1}{\sqrt{3}}\]

Best ResponseYou've already chosen the best response.0think about where sine and cosine have values that involve \[\sqrt{3}\] and make sure that \[\frac{\sin(x)}{\cos(x)}=\frac{1}{\sqrt{3}}\]

Best ResponseYou've already chosen the best response.0there are really only two places to look. it is either \[\frac{\pi}{6}\] or \[\frac{\pi}{3}\] because they are the only ones that involve \[\sqrt{3}\]

Best ResponseYou've already chosen the best response.0looks just like cosine, but shifted left \[\frac{\pi}{3}\] units, and goes from 3 to 3 instead of from 1 to 1
