What is the difference between matrices and determinants?
Both matrix and determinants are the part of business
mathematics. Both are useful for solving business problem. Both are
helpful for calculation of each other. For calculation of inverse
of matrix, we need to calculate the determinant. For calculating
the value of 3X3 matrix or more matrix, we need to divide
determinants in sub-matrix. but there are many differences between
matrix and determinants which we can explain in following
points.
1. Matrix is the set of numbers which are covered by two
brackets. Determinants is also set of numbers but it is covered by
two bars.
2. It is not necessary that number of rows will be equal to the
number of columns in matrix. But it is necessary that number of
rows will be equal to the number of columns in determinant.
3. Matrix can be used for adding, subtracting and multiplying
the coefficients. Determinant can be used for calculating the value
of x, y and z with Cramer's Rule.
