Chapter 2
IN THIS LESSON
Represent a linear map with a matrix and test injectivity and surjectivity.
This summary guides you step-by-step through the analysis of a linear transformation. You will learn how to build its matrix, test injectivity and surjectivity, compute the kernel and image, and understand the effect of composition. The method is fully explained, with a complete example at the end. Represent a linear map with a matrix and test injectivity and surjectivity.
