I'm just doing this question that says:

Solve for Θ to the nearest hundredth, where 0 ≤ Θ ≤ 2π

3tanēΘ - 2tanΘ = 1

The answers areπ/4, 2.82, 5π/4, and 5.96

I don't know how they got 2.82, or 5.96

I factored (3tanΘ+1)(tanΘ-1)

tanΘ = 1

then I used the special triangles, in the first and third quadrant to get π/4, and 5π/4.

what do I do about

tanΘ = -1/3?
