NettetPreface Overview ¶ permalink The Subject of This Textbook. Before starting with the content of the text, we first ask the basic question: what is linear algebra?. Linear: having to do with lines, planes, etc. Algebra: solving equations involving unknowns. The name of the textbook highlights an important theme: the synthesis between algebra and geometry. NettetLinear Transformations preserve the operations of vector addition and scalar multiplication A mapping T: Rn to Rm is onto Rm if every vector x in Rn maps onto some vector in Rm If A is a 3 x 2 matrix, then the transformation X to Ax cannot be one to one Not every linear transformation from Rn to Rm is a matrix transformation Nettet4. jan. 2024 · One-to-one: T: Rn → Rm is said to be one-to-one Rm if each b in Rm is the image of at most one x in Rn.
