Er, you got them wrong. dtd​(ke−t)=−ke−tî€ =−tke−t
Back to the basics then!! how is that the case? (Apologies we have been thrown into FP2 without doing C3/4 so I'm having to pick up all the differentiation rules as I go)

I don't have a choice - our school is making us do it this way! only other way would be to learn the calculus off my own back which I'd need to allocate time for which I don't really have right now
Awesome thank you, also I might be wrong but for the second part I got A = -5/12 and B = -1/4, then plugged that back into the comp function and particular integral to get x = -5/12 e^7t - 1/4 e^-3t + 5/3 e^-t

If you haven't done all of the differentiation and integration chapters, don't start on second order differential equations yet, solidify your knowledge on the necessary core stuff first.
That's not what I got, the power of 7t seems wrong.

Yeah I didn't mean 7t! & we have gone over all the chain rule, product rule etc quickly, I get it, I just need to put it into practice a few more times get fully comfortable with it! Thanks, I was able to do the rest of the worksheet relatively easily!
