In this tutorial we derive and apply a transformation matrix that can rotate a point any number of degrees about the origin.
In this tutorial we talk about how to find the equation of the image of a curve after a linear transformation. We use a reflection in the x axis as an example but the same steps will work with any sort of transformation.
Today we talk about a generic way for finding the transformation matrix of any linear transformation such as reflections or rotation by x degrees.
Today we talk about how to write a linear transformation as both an algebraic equation and a matrix equation, using the reflection in the x axis as an example.
In this lesson we talk about how to translate a curve and find the equation of the image.
In this lesson we talk about how to translate a point using matrix, and use this concept to translate a set of points.
In this lesson we discuss what the determinant of a matrix means, what it means when the determinant is equal to 0 and why you should calculate it before finding the inverse.
In this tutorial we learn how to use Gaussian Elimination to find the inverse of a 3×3 matrix.
In this tutorial we show you how to solve matrix equations in the form AX=B using Gaussian Elimination (where A, B are known matrices and X is the unknown matrix).
In this tutorial you can see how Gaussian Elimination can be applied to solve a system of simultaneous equations with 3 variables.
