sec(3θ)=-1

sec (3 θ) = - 1

θ = \frac{π}{3} + \frac{2 πn}{3}

Solution steps

sec (3 θ) = - 1

General solutions for

sec (3 θ) = - 1

3 θ = π + 2 πn

Solve

3 θ = π + 2 πn : θ = \frac{π}{3} + \frac{2 πn}{3}

θ = \frac{π}{3} + \frac{2 πn}{3}

x, 2 sin (x) = 0

y, arctan (x + y) = x

sin (x) = 2.4

6 cos (θ) - 5 = 0

sin (t) = - \frac{1}{2}
