(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(1 pt) Compute the 9th derivative of:

f(x) = [tex]\frac{cos(6x^4)-1}{x^7}[/tex]

at x=0.

2. Relevant equations

Hint: Use the MacLaurin series for f(x).

3. The attempt at a solution

I have tried many weird ways and cannot come up with the correct numerical answer. I've gotten 0 each time and it still comes up as wrong. Please help point me in the correct direction, even if it is only a verbal explanation!

Thanks so much
