All you have to do is derivative tan9x/x². Do you know how to? No?

Do you know quotient rule?

I know what it is just no how to use it here. Would it be 1 times 9?

No. I don't

First, we derivative tan(9x). We only need to derivative tan and left 9x untouched. Is this clear?

Okay, yes.so then I have that - tan9xtimes 2x

Thank you for your help but at this point I just can't do this.
