The Leibniz formula and the Laplace formula are two commonly used formulas. For example, given two matrices A and B, where A is a m x p matrix and B is a p x n matrix, you can multiply them together to get a new m x n matrix C, where each element of C is the dot product of a row in A and a column in B. Matrices are often used to represent linear transformations, which are techniques for changing one set of data into another. If you have no idea how I did what I just did, go learn how to multiply matrices, or get a graphing calculator (like the TI 84+). When referring to a specific value in a matrix, called an element, a variable with two subscripts is often used to denote each element based on its position in the matrix. Just select the value of q and the direction you want to go. We will also need to know that A is invertible (this means it must have an inverse), . a 4 4 being reduced to a series of scalars multiplied by 3 3 matrices, where each subsequent pair of scalar reduced matrix has alternating positive and negative signs (i.e. on Introduction.
