Is this a use of the Squeeze Theorem?

Question

Two broadcasting signals signals and signal b have amplitudes that can be modeled by mathematical equations. we will attempt to show that signal a and signal b have the same amplitude at some point in time. signal a has a frequency that oscillates according to the equation fa(t)=sin(t) and signal b has a decaying amplitude that follows the equation fb(t)=e^-t, where t is the number of seconds since broadcast, t>=0. use a theorem from class to show that these two signals will have the same amplitude at some time.

Answer 1

i would perform a(t)-b(t) and show that the sign changes. indicating point where a=b
