Two waves with different periods are described mathematically by: y3 = (7.0 m)cos[ 2kt/(3.0 ms) - k/2 ] y4 = (2.0 m)cos[ 2kt/(3.1 ms) V 3k/2] What is the beat frequency for these two waves?

Dont forget the influence the federal and state governments have on budgets. Both supply money with "strings" attached. Those strings greatly influence subsequent actions. "Strings" attached to Chapter I, or Title VIII, or Special Ed, or 504 exemptions are great examples. ...
