Determinant solution of linear systems
WebTo solve a system of three equations with three variables with Cramer’s Rule, we basically do what we did for a system of two equations. However, we now have to solve for three variables to get the solution. The determinants are also going to be 3 × 3 3 × 3 which will … WebFor instance, in the subject of di erential equations, determinants appear in the solution of systems of linear di erential equations. An example of such is x0 = 3x 4y + z y0 = x 2y + 3z z0 = x 3y + 4z Another is the one whose solutions include sines and cosines, y00 = y. The determinant for a system of linear di erential equations is called ...

"When the determinant of a matrix is zero, the system of equations associated with it is linearly dependent; that is, if the determinant of a matrix is zero, at least one row of such a matrix is a scalar multiple of another." If the determinant is zero, one of the rows doesn't need to be a scalar multiple of the others.
