I've been trying to find the general formula for the following problem but I can't seem to find anything in common.
Find a general formula for f^k (x) (the kth derivative of f) if f = 1 / (x^2-1)
So I found f ' and I got:
f '' :
2 (3x^2-1) / (x^2-1)^3
so I'm having difficulty with finding the general formula.
I know the denominator changes you'll have (x^2-1) always, but since the power is always increasing so...you'll have something like...
