• Before introducing a?derivative, an understanding of a?limit?is helpful

What is a limit?

What might I be asked about limits?What is a derivative?

How are limits and derivatives linked?

What is the notation for derivatives?

What might I be asked about derivatives?

What is differentiation?

• Differentiation?is the process of finding an expression of the?derivative?(gradient?function) from the expression of a function

How do I differentiate powers of x?What might I be asked to do once I’ve found the derivative (gradient function)?

• The?derivative?can be used to find the?gradient?of a?function?at any point
  • The gradient of a function at a point is equal to the?gradient?of the?tangent?to the curve at that point
  • A question may refer to the gradient of the tangent
  • A GDC can be used to help find gradients or verify answers
