Question

How do you solve for x in 2x=sin(2x) ?

Answer 1

We can quickly see that `x = 0` is a solution. The graph confirms that it is indeed the only one.

graph{sin(2x) - 2x [-10, 10, -5, 5]}

On the graph you are looking for where `y = 0`. This is at, and only at `x= 0`.

Hopefully this helps!
