Tanner Fullmer reported two errors [2 Dec]:
Problem (4b) (the second b) it shows that a=3,b=4,c=0,d=5. It should be
a=3, b=4, c=5, d=0.
Problem (4c)(second c) key shows the original denominator as (s+2)^3
when from the problem the denominator should be (s+2)^4.
Problem (5b) has no key, because these problem types have been removed from midterm 3.
To work such problems, write the problem as 2tf(t)=exp(2t)sin(t)-exp(-2t)sin(t).
Then -2(d/ds)F(s)=1/((s-2)^2+1)-1/((s+2)^2+1) can be solved as a first order
quadrature equation with solution F(s)=0.5(arctan(s+2)-arctan(s-2))+c. The value
of c=0, because limit F(s) =0 as s -> infinity. See also final exam keys from
S2008.
