Find the general solution of each of the following equations:

2 tan x – cot x + 1 = 0


To Find: General solution.


Given: 2 tan x – cot x + 1 = 0 2tan2x – 1 + tan x = 0 2tan2x – 1 + 2tan x – tanx = 0 2tanx(tanx +1) – (1+ tanx) = 0


(2tanx-1) (1+ tanx) = 0 tan x = = or tan x = -1 = tan


Formula used: tan = tan = n , n I


x = n or x = n


So the general solution is x = nor x = n where n I
