2. Homework Equations

3. The Attempt at a Solution
I'm not sure how to separate this. Also, since the directions consist of only one word, I'm not sure if y(2)=2 is some kind of hint or an additional condition to be fulfilled. I'm wondering where to go after factoring t out of the top. Thanks.

Well after factoring... you separate (hence separable equations!)

[tex]\frac{dy}{y+3} = \frac{t}{t^2+1}dt[/tex]

Then integrate both sides.
y(2) = 2 is an initial condition, not a hint... After solving for y(t) you will have one arbitrary constant, which can be solved for using this condition.

Wow, that seems almost too easy. Thanks.
