This Exam talkback explores energy changes in undamped and damped oscillations. You will have encountered sinusoidal oscillations in the context of simple harmonic motion (SHM). Exponentials arise in damped oscillatory motion (and radioactive decay). Both present many mathematical difficulties for students, not the least of which is remembering to set your calculator to radian mode.
