=

 •  To
evaluate
F
[
a
x(t)
+
b
y(t)
],
we
can
evaluate
F[x(t)]
and
 F[y(t)],
and
then
sum
the
appropriately.
 •  In
some
cases,
it
may
be
easier
to
evaluate
F[x(t)]
and
F[y(t)]
 instead
of
F
[
x(t)
+
y(t)
],
for
example: 

 d ⎡ x(t )⎤ ⎦ dt ⎣ F [C + D exp(−kt )] = F [C ] + F [D exp(−kt )] = 0 − Dk exp(−kt ) 
 F [ x(t )] = ECSE‐200
