Question: Which of the following equations represents the position of a simple harmonic oscillator as a function of time?

Options:

1. x(t) = A cos(ωt + φ)
2. x(t) = A sin(ωt + φ)
3. x(t) = A e^(ωt)
4. x(t) = A t^2

Correct Answer: x(t) = A cos(ωt + φ)

Solution:

The position of a simple harmonic oscillator can be represented as x(t) = A cos(ωt + φ) or x(t) = A sin(ωt + φ).
