1. The problem statement, all variables and given/known data
Determine the solution of the IVP y' + 4ty = 4t, y(0) = 6

2. Relevant equations

3. The attempt at a solution
p(t) = 4t
g(t) = 4t

μ(t) = e$^{\int4tdt}$
= e$^{\int p(t)}$
= e$^{\int4tdt}$
= e$^{2t^{2}}$

is this all I need? because i did
$\frac{d}{dt}$(y * μ(t)) = p(t) * g(t)
and the professor made a big red X mark on it, so I am confused.

Hi DrunkApple!
nooo

you're multiplying the whole equation by e2t2,

so the RHS should be e2t2 * g(t), shouldn't it?
