In this video we are going to look at how to find the equation of a straight line that passes through two given points (coordinates). You should already know that a straight line follows the y=mx+c format, where 'm' is the gradient and 'c' is the y-intercept. Start by finding the gradient either usi

In this video we are going to look at how we work out whether a number is in sequence or not. We looked at finding the nth term rule, generating sequences from it and finding terms in a sequence from the nth term rule in part 1. Is 730 a term in the sequence 3n + 11? 730 isn’t the term, so we cannot

Our body is a pretty fantastic feat of engineering. But how does it work? How do all of the different components come together to keep us alive, keep us functioning and achieving our goals? In this video we are going to look at the levels of organisation in organisms, from smaller than cells to bigg
SOHCAHTOA, Pythagoras, sine rule and cosine rule and all things trigonometry actually have a lot of uses in “real life”. Such as working out distances to things, heights of buildings and mountains, navigation at sea. An important part of “useful” trigonometry are angles of elevation and depression.
The way we grow and develop in the womb is controlled by our DNA. Small sections of DNA, called genes, carry the code telling the body how to build itself. Usually this works fine, but sometimes those genes carry mistakes in their code. These mistakes, known as mutations, may have no effect, they ma
