MATHEMATICA suppose you have two sine wave x{t]= A sin[w t] with the same amplitude A=1, but diff frequencies w1 w2. Use Manipulate[Column[],{range w1},{range w2}] to illustrate teh beat caused by the interference in time of the two waves. label the axes. time goes from 0 to 10pi. each frequency goes from 0 to 10.
