Solve this equation for x:
Obviously, the solution is . This can be proven by graphing and .
But I can't find any proper ALGEBRAIC way to solve this equation. Any idea?
Take a positive value as a start. Then, take the result you get in the same formula again and again until you get consistent results.
For example, take the first as x = 1.5
Use this again,
Again and again, until you get 1.999 which is enough to say that x = 2
