Can you solve it, /sci/? This is a pretty hard problem.

>solving DEs analytically
As a computer scientist I laugh at you
*writes a numerical solution and fucks your gf while your trying to solve analytically*

It's something multiplied by cos x

>>8864620
i like to pronounce runge kutta like kraka toa

That's p.easy.
If you presume it's Acosx+Bsinx because obviously, and realise that the third derivative^4 won't have sin by itself, you can satisfy it with A=-1/2, B=0.
So -(1/2)cosx

Did I get baited or something?

>>8865055
baited into giving an incorrect answer perhaps

>>8865064
oh no

>>8864620
Reminder that people who use numerical solutions are impotent.

It can't be solved analytically.
Also, I know what that pic is from.

Use Laplace?
