sec^2(θ)-1=0

sec^{2} (θ) - 1 = 0

θ = 2 πn, θ = π + 2 πn

Solution steps

sec^{2} (θ) - 1 = 0

Solve by substitution

sec (θ) = 1, sec (θ) = - 1

sec (θ) = 1 : θ = 2 πn

sec (θ) = - 1 : θ = π + 2 πn

Combine all the solutions

θ = 2 πn, θ = π + 2 πn

2 sin (θ) cos (θ) = - sin (θ)

6 cos (c) - 4 = cos (c) - 9

sec (θ) = \frac{7}{6}

2 cos^{2} (x) + 7 sin (x) - 5 = 0

\frac{( cos ( x ) cot ( x ) )}{1 - sin ( x )} = 3
