Best ResponseYou've already chosen the best response.1ok replace theta with x \[\Large 3\tan\left(\frac{1}{3}\theta\right) = 8\] \[\Large 3\tan\left(\frac{1}{3}x\right) = 8\]

Best ResponseYou've already chosen the best response.1then subtract 8 from both sides \[\Large 3\tan\left(\frac{1}{3}x\right) = 8\] \[\Large 3\tan\left(\frac{1}{3}x\right)8 = 88\] \[\Large 3\tan\left(\frac{1}{3}x\right)8 = 0\]

Best ResponseYou've already chosen the best response.1now graph `y = 3*tan(1/3x)8` into a graphing calculator here's a free one to use if you don't have a graphing calculator https://www.desmos.com/calculator

Best ResponseYou've already chosen the best response.0if you are being asked to solve, why not graph y = 8 and \[y = \tan(\frac{x}{3})\] and find the points of intersection in the given domain.

Best ResponseYou've already chosen the best response.1@campbell_st it should be `3tan(x/3)`

Best ResponseYou've already chosen the best response.0that is weird mine will not give me that graph. so approx 5.9 and 3.7

Best ResponseYou've already chosen the best response.1focus on the interval from 0 to 2pi 2pi = 6.28 so you're only focusing on roots between 0 and 6.28
