In part 1 we discussed reflection in the x axis. In this lesson we show you how to construct the transformation matrix for reflection in the y axis. Next lesson we will do reflection in the line y=x.
In this series we’re going to focus on constructing the transformation matrix for reflections. Start with reflecting in the x axis, which we have touched on previously. In subsequent lessons we’re going to talk about reflection in the y axis, reflection in the line y=x, and reflection in the line y=mx.
In this tutorial we rotated the line y=2x by 25 degrees about the origin and found the image of the line to be y’=37.25x’. We show you how to do it step by step.
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.
