Answer: In 9–14 use the Laplace transform to solve the
Chapter 7, Problem 13E(choose chapter or problem)
In Problems 1–8 use Theorem 7.4.1 to evaluate the given Laplace transform.
\(y^{\prime \prime}+16 y=f(t)\), y(0) = 0, \(y^{\prime}(0)=1\) where \(f(t)=\left\{\begin{array}{lr}
\cos 4 t, & 0 \leq t< \\
0, & t \geq
\end{array}\right.
\)
Text Transcription:
f(t)={{array} lr cos 4t, & 0 leq t<0, & t geq {array}.
