    how to you find theta you mean? use arctan aka tan^-1

    well 5pi/6 is one of the solutions so how would i write a formula solution?

    sqrt3/3 = sqrt3/(sqrt3)^2 = 1/sqrt3 tan theta=1/sqrt3 so the answer is 30

    (1/6)*Pi and there ar an infinite amnt of solotions. Cuzz it is a trig function.

    other wise just use calc in radian mode to get tan(3√/3)=0.6513878868

    well thats not what im looking for, thank you. the answer on the back of my book says theta=5pi/6+kpi and i dont know how they got that answer

    the + kpi just means that every k_pi it repeats.

    how do you get 5pi/6?

    well when I and edwardp did it we used calculators to find arctan and it gave us (1/6)*Pi which is pi/6 Put since it is repeating. I assume that 5pi/6 is also an answer. Just my guess.
