 # Sketching Graphs – 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 – 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 – 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 # Representing Inequalities Graphically – 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 # Career Paths – Post 16 Options: Alternatives to a Full-Time University Course

Have you considered alternative choices than going straight to university after 6th form? Here we provide some of the alternative, post-16 options available to you, to help you to make an informed choice. Continue reading Career Paths – Post 16 Options: Alternatives to a Full-Time University Course # Stealth Quadratics – A Level Maths Revision

To solve stealth quadratics (or “disguised quadratics”), you begin by making a substitution. This substitution will turn the stealth quadratic into a normal-looking quadratic, which you can then factorise and solve. Continue reading Stealth Quadratics – A Level Maths Revision # Tangents and Normals to a Curve – A Level Maths Revision

Finding the derivative of a function allows you to find the gradient of any point on a curve. If you can find the gradient, you can find the equation of tangents and normals to a curve at a given point. This A Level revision blog will explain how to do this. Continue reading Tangents and Normals to a Curve – A Level Maths Revision
