How to find Theta so cos(Theta) = 1/2 ?

Where do Sin, Cos and Tan Actually Come From - Origins of Trigonometry - Part 1

Why does sine squared plus cosine squared equal 1?

Prove that 1+cosx=2cos^2(x/2) and 1-cosx=2sin^2(x/2) trigonometric identites

1-cosx = 2sin^2(x/2) trigonometric identites proof || 1-cos theta

root ( 1 - cos theta )/(1+cos theta) = cosec theta - cot theta | Trigonometry class 10

1+cosx=2cos^2(x/2) trigonometry identites solve || 1+cos(theta)
