I can't find an easy way to use the integrating factor to solve this question, any ideas?
The i.f is obviously exp{(x^4)/4} but I don't know where to go from there. thanks
Hello, i_zz_y_ill!
If you found the integrating factor,
. . the next few steps are part of the procedure.
Exactly where is your difficulty?
The I.F is obviously: .
but I don't know where to go from there. . You don't?
Multiply by the I.F. .
We have: .
Integrate: .
Therefore: .
