Real life applications of chain rule

The Chain Rule can also help us deduce rates of change in the real world. From the Chain Rule, we can see how variables like time, speed, distance, volume, and weight are interrelated. A horse is carrying a carriage on a dirt path.

See below for an example.

Step-by-step explanation:

The distance travelled by a particle at time t is given by the function

f(t) = (2t - 2)^3  

Find it's velocity at time 2.

Finding the derivative using the chain rule:

f'(t) = 3(2t - 2)^2 * 2 = 6(2t - 2)^2

At time 2 seconds velocity = 6(2*2 - 2)^2 = 24.
