That looks right to me. Is there more to the question?

Yes, . I was told my solution is incorrect for some reason.

Ifyou've copied the question corectly then it's fine - were you given values to calculate k?

If you're not too busy, could you scroll down Exercise A, Question 12 and check if they did it wrong. I understand that they changed the dependent variable from y to t by mistake, but that's trivial.

@OP

Agree with everyone else - your working is fine

If they'd asked solve "dx/dy=...." then it would be a more interesting question, more in line with their given solution (apart from the "t").

Their working does not fit their question ... have they miscopied the exercise?

Needs to be dx/dy or dx/dt if they meant t.
