This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work.
In this video we’re going to discover how to factorise quadratics that don’t have 1 as the coefficient of the x-squared term. These are called non-monic quadratics. We can do it by trial and error and just spotting the factors, but this takes a lot of trial an error. Luckily there is a different method we can use instead, which we will looks at in this video.
This video explains how to find factors.
This podcast (audio) file explains how electric current can be obtained from the sun through the solar panel using direct illumination of the sun rays
Video 1: Introduces the concept of prime factorisation
Video 2: Examples of prime factorisation
Video 3: Common mistakes made relating to prime factorisation
In this course you will learn how to:
Electrical devices convert the electrical energy carried by the charges into other types of energy such as heat, sound, and motion. Components in the appliance resist the flow of charge and are referred to as resistors. In this unit1 you will understand what resistance is, the factors that affect the resistance and the relationship between resistance and current.
