1.3 Solving Systems of Linear Equations: Gauss-Jordan …
www.math.tamu.eduTo write a system of equations as an augmented matrix, line up all the variables on one side of the equal sign with the constants on the other side. Then, form a matrix of numbers with just the coe cients and constants from the equations. Write the following systems using augmented matrices. 3x 4y = 12 3x+ 2y 6z = 14 2x 4y = 9

2.5 Inverse Matrices - MIT Mathematics
math.mit.edu2.5. Inverse Matrices 81 2.5 Inverse Matrices Suppose A is a square matrix. We look for an “inverse matrix” A 1 of the same size, such that A 1 times A equals I. Whatever A does, A 1 undoes. Their product is the identity matrix—which does nothing to a vector, so A 1Ax D x. But A 1 might not exist. What a matrix mostly does is to multiply ...

Reading assignment Read [Textbook, Examples 2-10, p. 365-]. 6.1.3 Projections along a vector in Rn Projections in Rn is a good class of examples of linear transformations. We define projection along a vector. Recall the definition 5.2.6 of orthogonal projection, in the context of Euclidean spaces Rn.
