On a circle, the tangent is always perpendicular to the radius. We use this key piece of information when finding the equation of the tangent. We then use our knowledge of the equation of a circle, and the equation of straight lines (y = mx + c) to find the equation of the tangent. Equation Of A Ci

Every operation has an opposite. With functions the opposite is called the inverse function. It undoes the function and returns you to the initial input. There is a simple process to follow to find the inverse of any function which we look at in this video. 1) Start by writing the function as y=

Completing the square is another way of solving quadratics (as well as by factorising and by using the quadratic formula). Completing the square will always work, whatever the quadratic (whereas factorising does not always work). Completing the square also helps us when sketching the graph, as it

You might have noticed that if you are trying to boil a lot of water it takes longer than if you only wish to boil a small amount of water. This is all because of something called ‘heat capacity’. Keep watching to learn more. Before we get into the details, it is important to realise that there i

Learn about graphs. In this second part introductory video we will look at the equation of horizontal lines and vertical lines. We will also have a quick look at two important diagonal lines. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific o
A hormone is a chemical messenger that is secreted (or released) into our bloodstream by specific organs known as glands. Hormones regulate (or control) many processes in our body, including blood glucose levels, water content in blood, general growth, and blood pressure – just to name a few. They
In algebra, we replace a letter with numbers in the process known as substitution. Given the formula A = 1/2bh, if the base is 5cm and the height is 10cm, then the area is ½ X 5 X 10 because we have replaced the b with 5 and the h with 10. You just need to be be careful with negative numbers: it is
