WebDefinition. Let A be an n × n (square) matrix. We say that A is invertible if there is an n × n matrix B such that. AB = I n and BA = I n . In this case, the matrix B is called the inverse of A , and we write B = A − 1 . We have to require AB = I n and BA = I n because in general matrix multiplication is not commutative. WebA complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i 2 + 1 = 0 is imposed. Based on this definition, …
