(please solve within 15 minutes I will give thumbs up thanks)
To solve
y' = e +y– 1
we first rewrite the equation in the form
dy - +y-1,
dz
and then
(1 – e – y)dz + dy = 0.
It follows that the equation is
If we choose
H(z) = e=
then we obtain
e "(1- e – y)dr +e*dy = 0,
which is
Hence, the function
µ(z)
is an
