2cos(5θ)=0

Solution

2 cos (5 θ) = 0

Solution

θ = \frac{π}{10} + \frac{2 πn}{5}, θ = \frac{3 π}{10} + \frac{2 πn}{5}

+1

Solution steps

2 cos (5 θ) = 0

Divide both sides by

2

cos (5 θ) = 0

General solutions for

cos (5 θ) = 0

5 θ = \frac{π}{2} + 2 πn, 5 θ = \frac{3 π}{2} + 2 πn

Solve

5 θ = \frac{π}{2} + 2 πn : θ = \frac{π}{10} + \frac{2 πn}{5}

Solve

5 θ = \frac{3 π}{2} + 2 πn : θ = \frac{3 π}{10} + \frac{2 πn}{5}

θ = \frac{π}{10} + \frac{2 πn}{5}, θ = \frac{3 π}{10} + \frac{2 πn}{5}
