Derive Formulae | Algebra | Maths | FuseSchool

We can derive expressions and equations from sentences, and also we can derive formulae such as area and volumes, or quadratics. In this video, we're going to look at deriving formulae. You are usually given information in a diagram or sentences and asked to "show that". Ignore the "show that" as that is the final answer that we're trying to get to. Use the information given to create an equation, which then usually will need rearranging to get to the 'show that' answer. Take these questions step by step, and do not pay much attention to the "show that" information until the end. If in the question you are told the area for example, then that will be what your equation equals and you need to create an expression to find the area. Our teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT. VISIT us at, where all of our videos are carefully organised into topics and specific orders, and to see what else we have on offer. Comment, like and share with other learners. You can both ask and answer questions, and teachers will get back to you. These videos can be used in a flipped classroom model or as a revision aid.

Equation Of Parallel Lines | Graphs | Maths | FuseSchool

In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value. VISI
