Exponential functions are functions where the input occurs as a power. They are particularly useful in modelling real-life situations where the rate of growth or decay depends on the size of a starting quantity. Exponential functions are closely related to … Continue reading Exponential Functions – A Level Maths Revision
Differentiating a function provides information about the gradient, or rate of change, of the function. You can use differentiation to work out whether you are dealing with increasing or decreasing functions. This helps when sketching functions, when modelling or when … Continue reading Increasing and Decreasing Functions – A Level Maths Revision
This blog explains how to use position vectors to describe the position of a point from a fixed location. If your vector knowledge is a little rusty, it might be worth checking back over our blogs on 2D vectors and … Continue reading Position Vectors – A Level Maths Revision
This blog will explain how to use trigonometric identities to arrange linear and quadratic trigonometric equations into a form you can more easily solve. It will help if you’re already confident with how to solve a trigonometric equation – if … Continue reading Trigonometric Identities – AS Level Maths Revision
A stationary point of a curve is a point on the graph where the gradient is 0. There are three different types of possible stationary points: The local maximum and local minimum are sometimes referred to as turning points. For … Continue reading Stationary Points – A Level Maths Revision
Sketching graphs is a useful skill when you need to check the overall shape of a graph, but don’t need to plot it perfectly. This blog describes sketching graphs of cubic, quartic and reciprocal curves (you should have already learnt … Continue reading Sketching Graphs – A Level Maths Revision
The factor theorem is a quick way to find linear factors of a polynomial. It can be used alongside your preferred method of polynomial division to fully factorise polynomials (we also have a full blog on how to factorise cubics). … Continue reading The Factor Theorem – A Level Maths Revision
Algebraic division, or polynomial division, allows you to divide one polynomial expression by another. There are a number of different ways of carrying out algebraic division: Below are some examples using all three of these methods – chose the method … Continue reading Algebraic Division – A Level Maths Revision
It is possible to solve linear and quadratic inequalities graphically, using graphs to show the regions that satisfy single or multiple inequalities, as well as algebraically. Consider the two shaded regions below: When drawing inequalities graphically, you can either shade … Continue reading Representing Inequalities Graphically – A Level Maths Revision
