121F3 Approximation and Errors

Course Overview

In this Grade 11 mathematics course, you will gain essential skills in understanding and managing errors in mathematical calculations. This course will help you develop a strong foundation in error analysis, approximation techniques, and accurate computation. By the end of the course, you will be able to identify and manage different types of errors, such as round-off, truncation, absolute, and relative errors, ensuring your calculations are as precise as possible.

The course begins with foundational skills in using calculators effectively, teaching you to perform complex calculations with accuracy. You will then explore methods of estimation and approximation, which are useful in scenarios where exact values are either unnecessary or impractical. These skills will enable you to make quick, reasonable assumptions that simplify complex problems.

As you advance, you will dive into different error types, learning to calculate absolute, relative, and percentage errors accurately. You will also understand how errors propagate through calculations, especially in multiplication and division, where even small inaccuracies can compound and affect results. Through practical examples and exercises, you will see how these concepts apply in real-world contexts, such as in science, engineering, and everyday problem-solving.

This course will equip you with essential tools to manage and minimize errors in your calculations, boosting your confidence and accuracy in mathematical tasks.
