Question$2 x-1=2 \sin x+\cos x$

Studdy Solution
Verify the solution(s) found in Step 2 by substituting back into the original equation to ensure both sides are equal.
For example, if a solution $x = a$ is found, check:
$$2a - 1 = 2 \sin a + \cos a$$
If the equality holds, then $x = a$ is a valid solution.
Since this problem involves transcendental equations, exact symbolic solutions may not be easily obtainable, and numerical approximations are typically used.
