q11

Sometimes the function we need to find the Laplace Transform of is a combination of functions (aka: 2 or more functions added
together), a constant multiplied by a function, the derivative of a function, etc. so we have to use some additional rules in addition
to the rules used on the previous questions in order to find the Laplace Transform.
f(1) = 314 + 1
Use the Laplace Transform properties table to convert this function into F(s).
LAf(1) + 8(t)} = L{f(1)} + Z{ 8(1)}
L{C f(t)} = CLs(1)}
g{eA'f(1)}(s) = 21s() ) (s – A)
L{f (1))(s) = s L{f(t)} - f(0)
L{f"(1)} (s) = s2 L{f(1)} - Sf(0) - f"(0)
L{f"(1)}(s) = sN Lif(i)} - sN - !f(0) - sN - 2f (0) - sN -(0)
