Let ƒ be a function with domain R, and let a e R. Determine if the following statement is true or false. If lim f(x) = 00, then lim cos(f(x)) does not exist. If you believe it is false, provide a counterexample and explain why it works. If you believe it is true, prove it directly from the definitions of the statements involved (i.e., the definition of the first limit being infinity, and the definition of the second limit not existing).
