Applications of Differentiation

Applications of Differentiation

Basics of Differentiation

  • Understand that differentiation is a calculation to find the rate at which a quantity is changing.
  • Be sure to know the “Power Rule”: For any real number n, the derivative of x^n is n*x^n-1.
  • Recall the rules of differentiation involving addition, subtraction, multiplication, and division.

Differentiating Basic Functions

  • Grasp being able to differentiate simple power functions, like x^2, which becomes 2x after differentiation.
  • Gain a mastery in differentiating constant multiplying functions, like 5x^3, which becomes 15x^2 after differentiation.

Differentiation Rules and Techniques

  • Learn the product rule for differentiation which allows you to differentiate products of two or more functions.
  • Familiarise yourself with the quotient rule which enables the differentiation of fractions where both the numerator and the denominator are functions.
  • Remember and apply the chain rule which allows you to differentiate composite functions.

Applications of Differentiation

  • Understand how differentiation can be used to find stationary points, i.e., maxima, minima and points of inflection, on a curve.
  • Use differentiation to find the tangent or normal to a curve at a particular point.
  • Practice using differentiation to solve problems involving rates of change.
  • Extract or approximate rates of change from real-world contexts and interpret them appropriately.
  • Comprehend that differentiation can be used to find velocity from displacement, acceleration from velocity, and other similar real world applications.
