Multiplying both sides by gives
so that substituting and hence
gives the linear ODE,
Now multiply both sides by to get
so that the left side condenses into the derivative of a product.
Integrate both sides, then solve for , then for
:
We have:
So: w = 15 is not a solution of the inequality.
Ok done. Thank to me :>
