... For SHM, the period does not depend on the amplitude. For a pendulum with small , this is true, so a pendulum exhibits SHM for small displacements. For large (greater than 15 degrees or so) the smallangle approximation is not valid and the period does depend on the amplitude (max). Example 11-8 ...
