cos (θ) = \frac{1}{7}

Allgemeine Lösung für

cos (θ) = \frac{1}{7}

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

θ = arccos (\frac{1}{7}) + 2 πn, θ = 2 π - arccos (\frac{1}{7}) + 2 πn

θ = arccos (\frac{1}{7}) + 2 πn, θ = 2 π - arccos (\frac{1}{7}) + 2 πn

sqrt(3)sin(2x)+3cos(2x)=0

3 sin (2 x) + 3 cos (2 x) = 0

3cos(θ)=2sin^2(θ)

3 cos (θ) = 2 sin^{2} (θ)

sin(x)-sin(x)cos(x)=0

sin (x) - sin (x) cos (x) = 0

(sqrt(6))/3 cos(x)= 1/(sqrt(2))

\frac{6}{3} cos (x) = \frac{1}{2}

2sin^2(θ)=-3sin(θ)-1

2 sin^{2} (θ) = - 3 sin (θ) - 1
