3sec(x)-cos(x)-2=0

3 sec (x) - cos (x) - 2 = 0

x = 2 πn

Solution steps

3 sec (x) - cos (x) - 2 = 0

Rewrite using trig identities

- 2 - \frac{1}{sec ( x )} + 3 sec (x) = 0

Solve by substitution

sec (x) = 1, sec (x) = - \frac{1}{3}

sec (x) = 1 : x = 2 πn

sec (x) = - \frac{1}{3} :

No Solution

Combine all the solutions

x = 2 πn

- 2 sin (t) = - 2

x, r^{2} = sin (2 x)

3 cos (3 t) = 0

2 cos (x) - 1 = 0, 0 \leq x \leq 2 π

18 cos (x) + 9 sin (2 x) = 0
