I'm stumped on a value that needs converting to an answer 0-2π

I have cos x = 1/√3 or tan x = √2/1

I come up with 54.7 degrees but obviously need to convert in to a radian value

Please let me know if you can help

Thanx

Why are you using degrees at all?

The answer is $x=\arccos \left( {\frac{1}{{\sqrt 3 }}} \right) = .955$

Thanx.
I just thought I would add it in the angle. I failed to mention that I have .955 value.
Where I'm stumped is converting this value into radians 0>2π.
Can you help with that

$0.995$ is the radian measure and $0\le 0.995\le 2\pi~.$
