FORMULAS TO REMEMBER
L(eat f(t)) = F(s-a);
c(f(t-c)u(t)) = e "L(f(t));
b)
L-¹(F (s-a)) = eªt f(t) where f(t) = ¹(F(s))
¹(e-F(s)) = f(t-c)u(t) where f(t) = L-¹ (F(s))
L(f(t)8(t-c)) = f(c)e-c
(F(s)G(s)) = f(t).g(t)
L(8(t-c)) = e-s;
L(f(t) g(t)) = F(s)G(s);
f(t) + g(t) = [ f(t)g{t=t}dr = [*g(1)f(t−1)dr
Find the Laplace of the following functions.
a) J(t)=et et cosh(at)
K(t)= sin re-t+cos(t-1)dt
√ sine
