WebAug 19, 2016 · My question is use $L(f^{'}(t))=sF(s)-f(0)$ to show that $L(\sin^{2}(t))=2/(s^2+4)$. My approach was to integrate $\sin^2(t)$ to find $f(t)$, then use this to find $F(s)$ and $f(0)$. However, using that method, I find that the Laplace transform of $\sin^2(t)$ is $(s/2-1/2(s/(s^2+4))$, not $2/(s^2+4)$. WebHINT: Note that if F(s)=\int_0^\infty \frac{\sin(t)}{t}e^{-st}\,dt, then F'(s)=-\int_0^\infty \sin(t) e^{-st}\,dt=-\frac{1}{s^2+1} Now integrate F'(s) and apply \lim ... crow wing lake bertha homes for sale
