An alternative to repeated product rule for many factors is:
APartial fractional
BLog differentiation
CChain integration
DImplicit summation
Answer & Solution
Correct answer: B. Log differentiation
1. Taking logs turns products into sums.
2. Differentiating the sum is then far easier.
3. That method is logarithmic differentiation.
4. So the answer is log differentiation.
