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.
In this lesson we use buttons to display/hide content. We use a timer to run a specific function every time interval, and we also program a button to reload the page.
Today we talk about a generic way for finding the transformation matrix of any linear transformation such as reflections or rotation by x degrees.
In this lesson we talk about the concept behind Javascript programming – objects, properties and methods. Once you understand these concepts you will be able to cope with the following lessons a lot easier.
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 use arrays in conjunction with our maths quiz, so that solutions to all of our answers can be checked.
In this lesson we talk about how to translate a curve and find the equation of the image.
