Webcos(wt) = sin(wt+pi/2). This is what we call a phase shift of pi/2. Basically, a cosine wave is a sine wave pushed forward by pi/2 radians. The best way to a SH oscillator is either Asin(wt+phi) or Acos(wt+mu). To determine the phase shift, (phi/mu) we need boundary conditions. For example, we need to know what the speed of the oscillator is at ... WebThe function A sin wt is just the function A cos wt displaced by 90 degrees (graph it on a calculator, you'll see).
