2. Solve: 7tan(x) = -3 0 <= x <= 2pi

Answer: 2.74, 5.88(Rounded to two decimals)

My work:

tan(x) = -3/7

You need answers in , but when you take the inverse tangent, you get an answer in (because the latter is the range of the inverse tangent). Since our answer is negative, add to it to get . Then add to it again to get . Don't add a third time, because you'll then get an answer greater than .
