Homework Statement
Solving this differential equation
ty' + 2y = t^2 - t + 1
Homework Equations
Its linear so i set it up in linear form
y' + y(2/t) = t - 1 +1/t
The Attempt at a Solution
the integrating factor (u) = e ^ integral (ydt) = e^ integral (2dt/t)...
Here's the question, my book says u = t^2, and i just can't figure out how e ^ integral (2dt/t) is t^2
Its probably some stupid thing that I'm getting stuck on, thanks.
I know how to do this afterwards, i just can't for the life of god figure out why u = t^2
