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

Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles. We discovered these 4 theorems in part 1: Angle at the centre is double the angle at the circumference The angle in a semi-circle is 90 degrees Angles in the same segment are equal / Angles subtended by

In this video we look at a few keys words that you will come across throughout ecology. An ecosystem is made up of all of the communities that live in it, every single organism from small to big and lots of environmental factors like sunlight and shade in the woodland, streams and other things. It
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

Pi is the ratio of a circle’s circumference to its diameter. And it doesn’t matter how big or small the circle is, the ratio always stays the same: pi. That’s why pi is called a constant. Authors: ZDF/Terra X/Bilderfest/Lena Paul/Dirk Hagen/Saba Bussmann/Jochen Schmidt Translation and dubbing: alu
