Question
Determine all the possible values of x where 0 deg is more than or equal to x and x is more or equal to 360 deg such that
i'm not sure the solution, please correct it and how to find the x value,
2 tan x - 1 = cot x
solution:
(sec x -1)(sec x + 2) = 0
sec -1 = 0 , sec x + 2 = 0
sec x = 1 , sec x = -2
1/cos x = 1 , 1/cos x = -2
cos x = 1 or cos x = -2
then i don't know how to continue...
