# Thread: Find the derivative of f(x) = 5/(4x^2) using the limit process

1. ## Find the derivative of f(x) = 5/(4x^2) using the limit process

Find the derivative of the function f(x) = 5/(4x^2) using the limit process.

2. That is a lovely homework problem. Let's see your best efforts. Do you know the ratio to create?

Find the derivative of the function f(x) = 5/(4x^2) using the limit process.
Which formula have they given you to plug into? (There are at least two.)

How far have you gotten in plugging into that formula? Where are you stuck?
