Homework Statement
The problems are these:
y' + (3y/t) = (Sin(t)/t^3)
ty'-2y = t^3 + t^2, t>0
(general case)
y't^3+(3yt^2), y(2) = 0
(specific case)
Homework Equations
Basic ODE solving skills
The Attempt at a Solution
I can't figure out how to make the y's and y''s go on one side, and make the t's go on the other side of the equation. I think there is some completing a square trick or something to solve those.
Now, I did this problem earlier:
y + 3y = te^-3t
and integrated and multiplied both sides by two to get an implicit solution of:
2y+6y^2 = (-2/9)e^-3x (3x+1) + C
Did I do this correctly? As far as I now, all I have to do is integrate both sides (even though I don't see any dy's or dx's, so am confused).
