Find all solutions of the equation in the interval [0, 2 π). 2cos θ - √ 2 = 0
Write your answer in radians in terms of π. If there is more than one solution, separate them with commas.

θ =  

θ =

Step-by-step explanation:

2cosθ - √2 = 0

First, add √ 2 to both sides

2cosθ - √2 = 0

          +√2  +√2

2cosθ = √2

Divide both sides by 2

2cosθ/2 = √2 / 2

cosθ =

Use arccos to find θ

arccos() =  and   = θ

to determine the unit cost your would divide the total cost by the number sold.
