WebFeb 24, 2016 · The first notation is used to mean cos 2 θ = ( cos θ) 2 Your second notation will usually be read as cos θ 2 = cos ( θ 2) although it is sometimes preferred to use the notation in the right-hand side to be clear. They are not the same since ( cos θ) 2 = cos θ cos θ ≠ cos ( θ θ) = cos ( θ 2) Share Cite Follow answered Feb 24, 2016 at 9:10 StackTD Webcos (θ) = 4 5 cos ( θ) = 4 5 Take the inverse cosine of both sides of the equation to extract θ θ from inside the cosine. θ = arccos(4 5) θ = arccos ( 4 5) Simplify the right side. Tap for more steps... θ = 0.6435011 θ = 0.6435011 The cosine function is positive in the first and fourth quadrants.
