It is vital that you develop good ** graphing skills**. Graphs link geometry, algebra, calculus, and rates. Being able to

When you start on this journey of discovery at school, you will first learn how to think of a function as an *input-output machine*. You will use this ‘machine’ to calculate/find a series of *points.* You will list the coordinates of these points in a *table of values*, and then plot the points on a *graph,* and join those points with a *line/curve*. This is how you will learn to graph each function type. You will be shown that straight lines and their equations behave in certain ways, and learn about *intercepts* with axes and *gradients* of lines.

After that, you will start to discern that there are ‘families’ of functions and that all the graphs belonging to a particular family behave in similar ways. The basic six families that you will learn about are shown in the image above. It is important that you study all six of these ‘families’ and learn their characteristics, their idiosyncracies, and the particular features special to each one. I will try to add material to this section of the website to help you do all that.

By the time you have mastered all six graph types, you will also have learned how to move a graph anywhere on the plane that you wish, and how to change some of its key features. You will then be introduced to more graph types … logarithmic graphs and trigonometric graphs will come next. At every step you will consolidate some older skills even more, and learn new ones.

This is a wonderful and satisfying skill to develop and, like any skill (driving a car, swimming, dancing, etc.) you will get better at it with experience and practice … recognising that there can always be new surprises and new lessons around the corner! This is a life skill for training your mind to think abstractly, logically, and in pictures. I hope you are ‘up for the challenge’ and eager to earn your licence!

Hyperbolae and a Study of Asymptotes

From the beginning of my schooling I had struggled with Mathematics. Highly discouraged by my results, I grew to eventually hate Maths and lost all motivation to improve. Then part way through year seven my parents decided to send me to Crystal Clear Mathematics. Graeme was able to quickly identify areas I needed to improve and explain Maths in a way that finally made sense to me. I was able to understand Maths. This in turn then affected my confidence in my own ability.

Since working with Graeme I have gone from failing to significantly improved results. I now get As & Bs both in examinations and for assignment tasks. Graeme is patient, kind and his tutoring is individualised. He was so helpful and I am grateful for his help.
