Trigonometry?

3 ⤊

Solve for 0 ≤ Θ ≤ 2π
tan Θ = -3

I used a similar technique for a question: cos Θ = 1/4 but I couldn't match the books question, any suggestions?
thanks

tan θ = - 3
θ in 2nd and 4th quadrants.
θ = 108.4° , θ = 288.4°
or
θ = 1.89 radians , θ = 5.03 radians

Just find arctan(3), and add and subtract pi until you're past the boundaries you're given.
