-sec(θ)cot(θ)-sec(θ)=-2sec(θ)

- sec (θ) cot (θ) - sec (θ) = - 2 sec (θ)

θ = \frac{π}{4} + πn

Solution steps

- sec (θ) cot (θ) - sec (θ) = - 2 sec (θ)

Subtract

- 2 sec (θ)

from both sides

- sec (θ) cot (θ) + sec (θ) = 0

Factor

- sec (θ) cot (θ) + sec (θ) : - sec (θ) (cot (θ) - 1)

- sec (θ) (cot (θ) - 1) = 0

Solving each part separately

sec (θ) = 0 or cot (θ) - 1 = 0

sec (θ) = 0 :

No Solution

cot (θ) - 1 = 0 : θ = \frac{π}{4} + πn

Combine all the solutions

θ = \frac{π}{4} + πn

sec^{2} (a) = \frac{4}{3}

sin (5 x - 27) = cos (6 x + 13.6)

sin (x) = \frac{1}{cos ( - 10 0 ^{\circ} )}

3 tan^{2} (x) - 23 tan (x) + 1 = 0

tan (θ) = 0.6795786612
