2cos(3θ)=2

Solution

2 cos (3 θ) = 2

Solution

θ = \frac{2 πn}{3}

+1

Solution steps

2 cos (3 θ) = 2

Divide both sides by

2

cos (3 θ) = 1

General solutions for

cos (3 θ) = 1

3 θ = 0 + 2 πn

Solve

3 θ = 0 + 2 πn : θ = \frac{2 πn}{3}

θ = \frac{2 πn}{3}

Popular Examples

tan(θ)=2,0<θ<(pi/2),sin(θ/2)

tan (θ) = 2, 0 < θ < (\frac{π}{2}), sin (\frac{θ}{2})

sinh (a) = \frac{1}{2}

sin(x)=(-1}{\frac{sqrt(5))/2}

sin (x) = \frac{- 1}{\frac{5}{2}}

2csc^2(θ)-3cot(θ)+3=0

2 csc^{2} (θ) - 3 cot (θ) + 3 = 0

(2sin(x)+1)/(sqrt(cos(x)))=0

\frac{2 sin ( x ) + 1}{cos ( x )} = 0
