SUMMARY

The ordinary differential equation (ODE) ty' + 2y = 4t^2 can be solved by recognizing that the left side can be expressed as the derivative of a product: (t^2 y)'. By applying the fundamental theorem of calculus, the integral of the left side simplifies to t^2 y, allowing for straightforward integration. The solution involves integrating both sides, leading to the general solution for y in terms of t.

Homework Statement


Hi all, I'm trying to solve an ordinary differential equation. The problem is ty' + 2y = 4t^2


Homework Equations





The Attempt at a Solution



I got down to [tex]\int (t^{2})\frac{dy}{dt}[/tex] + [tex]\int 2ty[/tex] = [tex]\int 4t^{3}[/tex]

I am not sure about how to integrate the left side of the equation. The dy/dt make y make the problem confusing.

just recognize
[itex]t^2 y' + 2 t y = (t^2 y)'[/itex]
and use the fundamental theorem to say
[itex]\int f'(t) dt = f + C[/itex].
