I have no idea where to begin on this one to be honest.

Answer 2

@eliassaab sir i've no idea about the question can you please look in to the problem.

Answer 3

This question is from an exam that I did a month ago. Never seen a question like this previously, it caught me completely off guard.

Answer 4

\[
\frac{d \left(x^3-\sin
(x)\right)}{dx}-4
\left(x^3-\sin (x)\right)=\\-4
\left(x^3-\sin (x)\right)+3
x^2-\cos (x)=-4 x^3+3 x^2+4 \sin
(x)-\cos (x)
\]

Answer 5

Perhaps, it might better sense, if you see the question in its entire form

Answer 6

Apologies for not replying sooner, I was doing another question, thank you @eliassaab I'll see if I can work out the rest of the other parts of the question now
