The problem is to find an input vector which produces a result equal to. So in this case we set and solve for. However, in this case it will.

In the vector form of the line we get a position vector for the point and in the parametric form we get the actual coordinates of the point. We could just have easily gone the other way.

These are matrices that consist of a single column or a single row. The matrix version of the equation has its own geometric interpretation.

Example 6 Determine if the following set of vectors are linearly independent or linearly dependent. One can easily solve a system of linear equations when matrices are in one of these forms. This is always the case for a 2 by 2 matrix equation, if the columns of the matrix are multiples of one another.

This idea is illustrated in the interactive exercise below. Gaussian Elimination Write a system of linear equations as an augmented matrix Perform the elementary row operations to put the matrix into row-echelon form Convert the matrix back into a system of linear equations Use back substitution to obtain all the answers Gauss-Jordan Elimination Write a system of linear equations as an augmented matrix Perform the elementary row operations to put the matrix into reduced row-echelon form Convert the matrix back into a system of linear equations No back substitution is necessary Pivoting is a process which automates the row operations necessary to place a matrix into row-echelon or reduced row-echelon form In particular, pivoting makes the elements above or below a leading one into zeros Types of Solutions There are three types of solutions which are possible when solving a system of linear equations Independent.

We know that the new line must be parallel to the line given by the parametric equations in the problem statement. There is one more form of the line that we want to look at. Elementary Row Operations Elementary Row Operations are operations that can be performed on a matrix that will produce a row-equivalent matrix.

We already have a quantity that will do this for us. At this point all that we need to worry about is notational issues and how they can be used to give the equation of a curve. If it does give the coordinates of that point. The best way to get an idea of what a vector function is and what its graph looks like is to look at an example.

Here are the parametric equations of the line. Elementary Row Operations Elementary Row Operations are operations that can be performed on a matrix that will produce a row-equivalent matrix.

Note as well that a vector function can be a function of two or more variables. The desired result,will be shown in yellow. Moreover, the infinite solution has a specific dimension dependening on how the system is constrained by independent equations.

The only difference is that we are now working in three dimensions instead of two dimensions. We know that the new line must be parallel to the line given by the parametric equations in the problem statement.

To differentiate or integrate a matrix of this form all we do is differentiate or integrate the individual entries. Multiply an equation by a non-zero constant.

All elements above and below a leading one are zero. So, before we get into the equations of lines we first need to briefly look at vector functions. It can be anywhere, a position vector, on the line or off the line, it just needs to be parallel to the line. A matrix in row-echelon form will have zeros both above and below the leading ones.

There will be exactly one solution. We turn to the parametric form of a line. General Solutions of Systems in Vector Form MA We are looking for solutions to the system Ax = b, in column vector form in what follows. We wish to organize the vectors making up the solution into two types, what are called homogeneous and particular.

Finally, I understand how to use Gauss-Jordan elimination to change this to reduced row-echelon form: 1 6 0 11 0 0 0 1 -8 0 0 0 0 0 0 However, in an example solution that my instructor has prepared, this is then used to find the general solution in parametric form.

In the vector form of the line we get a position vector for the point and in the parametric form we get the actual coordinates of the point.

There is. Finally, I understand how to use Gauss-Jordan elimination to change this to reduced row-echelon form: 1 6 0 11 0 0 0 1 -8 0 0 0 0 0 0 However, in an example solution that my instructor has prepared, this is then used to find the general solution in parametric form. Often varieties of parametric RHS systems of equations can be reduced to the following standard form: AX = b + Dr, where A is an n by n non-singular matrix, the column matrix b the numerical value of the RHS, and diagonal matrix D contains the coefficients of the parameters r = [r1, r2, rn]T, respectively.

form a parametric representation of the unit circle, where t is the parameter: A point (x, y) is on the unit circle if and only if there is a value of t such that these two equations generate that point.
