Determinant information
WebSolve the system of equations using Cramer’s Rule: { 3 x + y − 6 z = −3 2 x + 6 y + 3 z = 0 3 x + 2 y − 3 z = −6. Cramer’s rule does not work when the value of the D determinant is 0, as this would mean we would be dividing by 0. But when D = 0, the system is either inconsistent or dependent. WebNov 30, 2016 · Cramer was the first to publish on the subject (1750). The theory of determinants is based on the work of A. Vandermonde, P. Laplace, A.L. Cauchy and C.G.J. Jacobi. The term "determinant" was first coined by C.F. Gauss (1801). The modern meaning was introduced by A. Cayley (1841).
