WebFree matrix inverse calculator - calculate matrix inverse step-by-step WebCalculate a determinant of the main (square) matrix. To find the 'i'th solution of the system of linear equations using Cramer's rule replace the 'i'th column of the main matrix by solution vector and calculate its determinant. Then divide this determinant by the main one - this is one part of the solution set, determined using Cramer's rule.
WebThe area of the little box starts as 1 1. If a matrix stretches things out, then its determinant is greater than 1 1. If a matrix doesn't stretch things out or squeeze them in, then its determinant is exactly 1 1. An example of this is a rotation. If a matrix squeezes things in, then its determinant is less than 1 1.
