There are no any formula of 2 cos x but there are some other formula for cos(2x) cos(2 x) = cos(2x) – sin(2x) Cos(2x)= 1 – 2 sin(2x) Cos(2x)= 2 cos(2x) – 1
Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. x 2 = arccos(0) x 2 = arccos ( 0) The exact value of arccos(0) arccos ( 0) is π 2 π 2. x 2 = π 2 x 2 … 2019-12-27 $$\sqrt[3.911]{\frac{1-x^2}{1+x^2}} \approx \cos{x}$$ Setting the above approximation $=x$ and solving can give a closed form solution that lies within 4 decimal points of the solution.
