That's more like it
I was working with a mechanics problem with polar coordinates and a very similar ODE arose (slightly easier)

So I could not possibly not make this question.

How did your step exams go?
Odd. Think i got grade 1 in step II but grade 2 in III. But lets see. I made a terrible choice of questions in III and was slower then I usually am.
Wbu?

I have no idea if there are alternatives ...

From my point of view, as the question ,maker it is difficult to see anything else apart from one method, because I started from the answer and worked "backwards".

I am guessing this is a hard question, soon to go into my Special papers.

By AM GM arithematic mean>=geometric mean
Let three numbers be a^3 b^3 b^3
Rewrite as (a^3+b^3+b^3)/3>=((abb)^3)^1/3

I think the forth last step (in the solution) has a "printing" error in it. Otherwise how did the 4/(k+4) turn into a 1/(k+4) . This also may have affected the paper, because then the 1/f(k) inside the bracket should be a 4/f(k) .

Silly error thank you for pointing it

Luckily it did not affect the method.
