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.
In this tutorial you learn to use the for loop to repeat an instruction a certain number of times. In this case we generated 20 random maths questions using the for loop.
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 improve on our quiz by generating 2 random numbers using the Math.random() function to make up the maths question. We then check our answer against the 2 variables to see whether we got it correct. A random maths addition quiz created!
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 lesson we talk about how to use the IF-else statement to output a message back to the screen based on what the user has input in the form.
