Algebraic manipulation of polynomials, including expanding brackets and collecting like terms, factorisation.

Graphs of functions

Sketching curves defined by simple equations. Knowledge of the term asymptote is expected.

Geometrical interpretation of algebraic solution of equations including use of intersection points of graphs of functions to solve equations.

Knowledge of the effect of simple transformations on the graph of y = f(x) as represented by y = af(x), y = f(x) + a, y = f(x + a), y = f(ax).

Condition for two straight lines to be parallel to each other.

Condition for two straight lines to be perpendicular to each other.

 

3 Sequences and series

Sequences, including those given by a formula for the nth term and those generated by a simple relation of the form xn+1 = f(xn).

The general term and the sum to n terms of the series are required.
