How do you differentiate using the chain rule?

In order to differentiate using the chain rule,you first need to know the chain rule. Chain rule : dy/dt * dt/dx = dy/dx.

It is basic multiplication to get rid of the common factor of 'dt' in both equations to give dy/dx.

You would begain by differentiating the general y = something t and x = something t. This will give you the dy/dt and dx/dt. You would then find th recepricol of dx/dt to give dt/dx. Then multiply with the dy/dt you found before. This is known as the chain rule.
