Consider the two harmonic motions (x_{1}(t)=frac{1}{2} cos frac{pi}{2} t) and (x_{2}(t)=cos pi t). Is the difference (x(t)=x_{1}(t)-x_{2}(t))

Question:

Consider the two harmonic motions \(x_{1}(t)=\frac{1}{2} \cos \frac{\pi}{2} t\) and \(x_{2}(t)=\cos \pi t\). Is the difference \(x(t)=x_{1}(t)-x_{2}(t)\) a harmonic motion? If so, what is its period?
