Overview
This resource introduces anti-differentiation, the reverse process of differentiation, as a foundational concept in integral calculus.
Students learn how to find the antiderivative of a given function, apply the power rule for integration, and interpret integration as the area under a curve.
Through step-by-step examples, this lesson helps students build a conceptual bridge between differentiation and integration while emphasizing correct notation and constants of integration.
Learning Objectives
By the end of this lesson, students will be able to:
- Understand anti-differentiation as the reverse of differentiation.
- Apply the basic power rule for anti-differentiation.
- Write general solutions including the constant of integration ©.
- Use anti-differentiation to find functions from their derivatives.
- Recognize the connection between definite integrals and the signed area under a curve.
What’s Included
- Concept introduction comparing inverse operations (functions and differentiation).
- Explanation and notation of the antiderivative ( F’(x) = f(x) ).
- Step-by-step worked examples finding general antiderivatives of polynomial functions.
- Practice problem solving for constants given initial conditions (e.g., ( y = 10 ) when ( x = 1 )).
- Transition from indefinite to definite integrals, introducing area interpretation.
- Visual demonstration of the definite integral as signed area between ( x = a ) and ( x = b ).
- Fully worked example computing the area under a curve between two bounds.
Topics Covered
- Definition of anti-differentiation.
