Solve on the interval [0, 2pi) : 3 sec x -2 = 1

First we rewrite the expression:
 3sec (x) -2 = 1
 3 (1 / cos (x)) -2 = 1
 3 (1 / cos (x)) = 1 + 2
 3 (1 / cos (x)) = 3
 (1 / cos (x)) = 3/3
 cos (x) = 1
 x = 2 * pi * n
 on the interval [0, 2pi):
 x = 0
 
 x = 0 on the interval [0, 2pi)

Hmmm i had this before , give me a sec

221,500 is the answer
