beyond simple fractional derivatives

I was able to deduce using highschool knowledge a formula for the n'th derivative of basic continuous functions.
for instance:
D^n[x^p]=p!*x^(p-n) /(p-n)!
D^n[a^x]=(ln(a)^n)*a^x
D^n[sin(x)]=sin(x+n*Pi/2)

also the product rule can be extended to nth derivatives

product rule:
D^n(f*g)=sum from i=0 to i=n of nCi*D^(n-i)(f)*D^i(g)

Can the reciprocal (and quotient rule using both product and reciprocal rules) and the chain rule be similarly extended for n'th derivatives?

No Ideas?? Is this in the wrong section?
