Using ICT in Maths. The 45th in Mr Barton's Autograph Video tutorial series. This week we continue our look at the world of 2D graphing by examining how we can use the tangent tool and the gradient function to investigate quadratic curves. This offers a slick way of illustrating why two quadratic curves have the same gradient function. Clicking on the web-link you can see all the videos in this series.

An excellent graphing tool to draw the graph for any polynomial function and find the equation of a tangent after drawing a tangent on the curve at any point. To get a better understanding by changing the parameters to draw any type of gradients such as positive, negative, or parallel to x-axis or y-axis and find the equation of tangents. The video explained everything step-by-step and showing different results by changing the parameters. So I found this video very interesting and it enhanced my understanding and knowledge and I must incorporate this Autograph software into my teaching.
very good.
