Math Problem Statement
but now you're on board the spaceship #1725486563, and the captain is asking to solve "ZP" (Z Planet) problem (you know what it means when captain is "asking"... that's an order):
Use the chain rule to find the derivative of f(x)=
f'(x)=
!!! The challenge is that the Chain Rule on Earth, f(g(x))'=f'(g)g'(x) , is "twisted" on Z planet as the following:
f(g(x))'= f'(g)/g'(x) (all the other rules have not been changed).
Solution
It looks like we're aboard spaceship #1725486563, solving the "Z Planet" problem where the Chain Rule is modified. On Earth, the Chain Rule is typically:
However, on Z Planet, it's twisted:
Given function:
Let's break it down.
Step 1: Identify the outer and inner functions.
The given function is of the form , where:
Step 2: Earth version of the derivative
First, calculate the derivative using Earth’s Chain Rule:
The derivative of with respect to is:
Now, compute :
Thus, the Earth version of the derivative is:
Step 3: Z Planet version of the derivative
According to Z Planet’s twisted Chain Rule, we divide by instead of multiplying by it. Thus, on Z Planet:
This is the derivative on Z Planet.
