Learn how to differentiate Composite Functions using the Chain Rule

Key Points

The Chain Rule is for differentiating composite functions only

Composite functions can appear in many ways so try to learn some common forms

The Chain Rule essentially says to differentiate twice – once for the inner and once for the outer function

These two differentiation results are then multiplied together

The ‘rules’ for differentiating Trigonometric functions is actually a specific use of the Chain Rule

A bracket with a power on it is another common function type for using the Chain Rule
