SUMMARY
The equation x - 2 Cos[x] == 0 cannot be solved using the Solve function in Mathematica due to its transcendental nature, which lacks an exact solution. Instead, users should utilize the FindRoot function, specifically FindRoot[x == 2 Cos[x], {x, 0}], where '0' serves as the initial starting point for the numerical solver. It is crucial to ensure that 'Cos' is capitalized in the command to avoid syntax errors.
