APFIVE Time to Maximum Displacement in SHM
The position of an object in simple harmonic motion is described by the equation $$x(t) = 0.05\cos(2\pi t + \frac{\pi}{4})$$, where $$x$$ is in meters and $$t$$ is in seconds. At what time $$t > 0$$ does the object first reach a position of maximum displacement from equilibrium?
