Hi, Could someone give me somw much needed guidance on the following question:
Differentiate: f(x) = 2cos(3x - 1)/3x ?
I'm struggling to start with this one.
Firstly does 2cos(3x - 1)/3x become: 2/3 xcos(1 - 3x), I'm trying to remove the division by 3x?
Can someone please give me some help so I can get on with this?
Thanks in advance.
