With your calculator, solve for $\displaystyle x$ over $\displaystyle 0 \le x \le 2\pi$.Problem:

$\displaystyle x-cos x = 0$

My first guess was to factor out $\displaystyle x$, but that would leave me with no cos value. Would that be permissible? Is not cosine value equal to cos 0? That's my only guess and I doubt it.Attempted Solution:

If anyone could help, I would greatly appreciate it.
