IB Math AI SL 5.4 – Tangents and Normals

Topic: Calculus
Level: IB Mathematics: Applications and Interpretation (SL)
File Type: Editable Slides / Lesson Presentation

Overview
This resource introduces tangents and normals to a curve as geometric applications of differentiation.
Students learn how to find the equation of a tangent line to a curve at a given point using the derivative as the slope, and how to determine the equation of a normal line as the perpendicular to that tangent.

The lesson bridges algebraic and geometric reasoning, showing how calculus connects to real-world interpretations of slope and direction.

Learning Objectives
By the end of this lesson, students will be able to:

  • Define the tangent and normal lines to a curve at a given point.
  • Calculate the slope of a tangent using the derivative ( f’(x) ).
  • Write the equation of a tangent line using the point-slope form.
  • Derive the equation of a normal line as the perpendicular to the tangent.
  • Verify results graphically using technology.

What’s Included

  • Definition and visual explanation of tangents and normals.

  • Step-by-step method to find the tangent line:

    1. Differentiate ( f(x) ).
    2. Substitute ( x = a ) to find the slope.
    3. Use the point-slope form to find the equation.
  • Worked example: finding the tangent and normal lines to a curve at ( x = 1 ).

  • Practice problem with guided solution and graph verification.

  • Visual illustration connecting the slope of the curve to the direction of tangent and normal lines.

Topics Covered

  • Tangent and normal line definitions.
  • Derivative as slope of the tangent.
  • Equation of a tangent line using point-slope form.
  • Equation of a normal line as perpendicular to tangent.
  • Graphical verification and use of technology.

Why You’ll Love It

  • Provides a clear conceptual and procedural foundation for slope-based calculus problems.
  • Integrates algebraic calculation with visual graphing interpretation.
  • Includes both step-by-step derivations and real-time graph verification.
  • Fully aligned with IB Math AI SL Topic 5: Calculus.
  • Ready-to-teach and adaptable for classroom or individual study.
