This is what I have so far

Solve C:

Now I'm having trouble isolating Y to get an answer.

Have I taken all the right steps so far, and if so how do I go about isolating Y?

Thank You for any help

there are 2 things on this one

1. Since this is a linear DE the whole problem can be solved easier using an integrating factor

http://www.mathhelpforum.com/math-he...ed0d1d14-1.gif is set up perfectly for this

with the integrating factor e^(.4*t^2)

However suppose you want to separate variables

2.first you were ok up to

http://www.mathhelpforum.com/math-he...6ea5c47b-1.gif

To integrate the left use u = 2 - 0.8y

you tried to write as dy/2 -dy/(.8y) which is not true - April 30th 2009, 01:57 AMKrooger
Whoa I didn't not even see that it was a integrating factor problem haha thank you very much.
