**drwls**, Wednesday, February 11, 2009 at 7:39pmNote that the equation can be rearranged and factored as follows:

tan^2x -tanx -2 = 0

(tanx -2)(tanx +1) = 0

tan x = 2 or -1

There are four angles between 0 and 360 degrees that are solutions. One of them is 135 degrees. Another is 63.435 degrees. See if you can find the others.
