i have f(t) defined piece-wise and continous..(adsbygoogle = window.adsbygoogle || []).push({});

f(t) = 0, t < 2pi

t-pi , pi <=t<2pi

0 , t >=2pi

i have so far g(t)=U_pi*f(t-pi)-U_2pi*f(t-pi)

if i do the laplace,

i get e^-pis/s^2-e^-2pis/s^2

in the book, they have

e^-pi*s/s^2 -e^-2pi*s/s^2 (1+pi*s)

I am not sure how they got the factor of (1+pi*s)
