IB Math AI SL 5.1 – Limits Topic: Calculus Level: IB Mathematics: Applications and Interpretation (SL) File Type: Editable Slides / Lesson Presentation Overview This resource introduces the concept of limits as the foundation of differential calculus. Students learn how limits describe the behavior of functions as inputs approach specific values, and how this concept leads to the definition of the derivative as an instantaneous rate of change. The lesson builds from intuitive examples to the formal definition of a limit, helping students understand the transition from average rate of change to instantaneous gradient through graphical and analytical reasoning. Learning Objectives By the end of this lesson, students will be able to: Describe the concept of a limit intuitively and formally. Recognize when a function is well-defined or undefined at specific points. Use limits to describe the behavior of a function as ( x ) approaches a value. Understand that the derivative is defined as a limit of the average rate of change. Interpret the derivative as both the gradient of a curve and a rate of change. What’s Included Conceptual introduction showing functions that are well-defined and undefined at certain points. Visual exploration of function behavior as ( x ) approaches a specific value. Intuitive definition of a limit followed by the formal epsilon-delta definition Examples illustrating how limits predict the behavior of functions near discontinuities. Step-by-step transition from average rate of change (secant line) to instantaneous rate of change (tangent line). Definition of the derivative as a limit Comparison of gradient behavior for linear vs. nonlinear functions. Topics Covered Concept and definition of a limit. Formal epsilon-delta definition. Average vs. instantaneous rate of change. Definition of the derivative as a limit. Interpreting limits graphically and analytically. Why You’ll Love It Establishes a clear conceptual foundation for all of calculus. Combines visual, numerical, and analytical approaches to limits. Smoothly bridges intuitive understanding with formal mathematical definition. Fully aligned with IB Math AI SL Topic 5: Calculus. Classroom-ready and ideal for interactive instruction or student exploration.

This resource includes: different types of slopes calculate slope from graphs, tables, pictures, and points undefined and zero slopes. Also, how to find a coordinate if given 1.5 points and the slope

This resource includes: graphing in slope intercept form on the coordinate plane determine slope and y-intercept from an equation write an equation given slope and y-intercept determine if lines have positive, negative, zero or undefined slope

Improper Integrals covers; Identify why a given integral is improper Understand and clearly demonstrate the limiting processes involved, using correct notation Identify when and why an improper integral does not have a finite value Identify the point(s) where the integrand is undefined Evaluate improper integrals where the integrand is undefined at a value in between the limits of integration. These PowerPoints form full lessons of work that together cover the full A level Further Maths course for the AQA exam board. Together all the PowerPoints include; • A complete set of notes for students • Model examples • Probing questions to test understanding • Class questions including answers • Individual whiteboard work • Links to exercises in ‘AQA approved textbooks by Camb uni Press’ these can easily be edited for your textbook The PowerPoints can be used in the lesson and also given to students that have missed a lesson Videos of the lessons are all on You Tube so you can see the PowerPoint lessons fully first I have added ‘Further Maths 5 - Matrices Transformation’ and ‘Further Maths 23 - Network Flows’ for free download Please leave a review as it will really help me to improve my resources

16 gradients clues, including negatives, positives, undefined and zero on a variety of scales. Work out the answer then find the next clue that has that answer at the top. Includes answer sheet and solutions. Also includes a letter on each clue that form an anagram to be solved: gradients are cool.

logarithmic derivatives practice- derivative sign chart this resource covers: how to find inflection points on a derivative graph first derivative and second derivative graph second derivative at point of inflection the second derivative be can undefined at an inflection point

This is a coloring activity on finding the slope of two points for 16 problems. Students will color the picture according to the correct answer for each problem. I used 8 colors in the design and I put in 2 different designs. The “A” design goes with the flower problems and the “B” problems go with the positive, negative, 0 and undefined sheet.
