1. ## Solving for X

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

$x-cos x = 0$

Attempted Solution: My first guess was to factor out $x$, 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.

If anyone could help, I would greatly appreciate it.

2. cos(x) is a function, so you can't factor x out of it. The problem clearly mention the use of calculator. Draw the graph of y=x and y=cos(x) and then find their intersection points in the indicated interval.
