 Title Description Co-ordinate Geometry Pre-Test This test assesses students for their grasp of year 8 co-ordinate geometry. Worked solutions included. Co-ordinate Geometry Proofs: Quad. Sufficiency Conditions Incorporates understanding of four-sided Euclidean figures with methods in co-ordinate geometry (gradients, distances, etc). Curve Sketching: Rational Functions Steps for how to accurately draw the graphs of rational functions (for instance, y = (x+1) / ((x-2)*(x-4)) ). Deriving the Index Laws The rules that apply when handling indices (exponents) are often learnt by rote without understanding where they come from. It's straightforward to see that they all arise from the basic definition of exponentiation.

Oblique Asymptotes Step-by-step guide of how to identify and locate the equations of asymptotes that are neither horizontal nor vertical. Solving Cubic Equations Guide on how to find the roots of a third-degree polynomial. Introduction to Solving Polynomial Equations Includes derivation of Remainder and Factor Theorem. Polynomials Topic Test Includes fully worked solutions. Synthetic Division Once you learn it, you'll never use long division to divide through polynomials again. Solving Quadratic Equations Overview of factorising, completing the square and quadratic formula to solve second-degree polynomials. Intercepts on Parallel Lines Derivation of the geometric theorem, "parallel lines preserve the ratios of intercepts on transversals". Weekly Quiz Template 9C (2010) template.
