periodic - How do I find the fundamental period of the given signal?


I am having a problem in finding the fundamental period of the signal x(t) given below: x(t)=2cos(45πt)sin2(163t)=2cos(45πt)12[1cos(323t)]=cos(45πt)cos(45πt)cos(323t)=cos(45πt)12{cos[(45π323)t]+cos[(45π323)t]}

Apparently the of last four, MgX2+ is closest in radius to LiX+. Is this true, and if so, why would a whole larger shell ($\ce{...
