Solution

2 + 2 cos (θ) = 4

Solution

θ = 2 πn

+1

Solution steps

2 + 2 cos (θ) = 4

Move

2

to the right side

2 cos (θ) = 2

Divide both sides by

2

cos (θ) = 1

General solutions for

cos (θ) = 1

θ = 0 + 2 πn

Solve

θ = 0 + 2 πn : θ = 2 πn

θ = 2 πn

sin^{2} (x) - 2 sin (x) = 3

sin(x+pi/3)= 1/2

sin (x + \frac{π}{3}) = \frac{1}{2}

(sin(47))/(12)=(sin(x))/(11)

\frac{sin ( 4 7 ^{\circ} )}{12} = \frac{sin ( x )}{11}
