Question

Use logarithmic differentiation to find dy/dx. y = (x + 1)(x − 4)/ (x − 1)(x + 4) , x > 4 dy dx =

Answer 1

Answer:

dy/dx = (x + 1)(x-4)/(x-1)(x+4)[1/(x+1) + 1/(x-4) -1/(x-1) -1/(x+4)

Step-by-step explanation:

Here, we want to find the derivative using logarithmic differentiation.

What we will do here is to first take the natural logarithm of both sides, then we proceed to differentiate afterwards.
