Question
Explain, using Theorems $4,5,6,$ and $8,$ why the functionis continuous at every number in its domain. State the domain.$L(t)=e^{-5 t} \cos 2 \pi t$
Step 1
The domain of this function is all real numbers, or $\mathbb{R}$, because there are no restrictions on the values that $t$ can take. Show more…
