Hi all (it has been a while again),(adsbygoogle = window.adsbygoogle || []).push({});

I have just started Universtiy and after my second lecture I was given a question sheet to complete in two weeks. I have completed 14 out of the 16 questions set, 2 of which I just haven't done yet and another will require a little more thought before I need some help.

The question I am having a problem with is this one:

4. Find f'(x) for each of the following f.

(d) [tex] f(x) = x^{sinh2x} [/tex]

I would give some sort of attempt, like you all expect, before I get any help but I am afraid I have never come across this sort of equation before. I really do not know where to start. I did think about letting u = sinh2x and doing a sustitution but I realised that would not work so I am really stuck. I can but assume I need some sort of rule or theorem that I have either not learnt or cannot find on the internet (and trust me, I have looked).

Any help would be greatly appreciated.

Cheers for now,
