The question is to find the solution for
for when y(1)=-1
here is my working
then by partial fractions the left hand side is
and right hand side is
so
raising by power of e
But this does not appear to me to be right, as the y term has fallen off all together, and I don't have the answer for this problem to check, plus am confused where the y(1)=-1 comes in.
1. You should quote the post you're referring to so that what you say can be understood.
2. If you're going to say something like this, you should back it up with a reason.
3. All forms of the solution given in this thread are correct, as can be easily confirmed by substitution into the given DE.
