The answer $\frac{\sin x}{x}$ is correct in many mathematical contexts, such as in limits, Fourier transforms, or signal processing problems involving sinc functions. If you'd like, I can delve into why this is the result, how it's derived, or where it applies.

Would you like a detailed explanation or have any specific questions?
