IGCSE Maths Edexcel B 4MB1

Scalar and vector quantities

Vectors will be in two dimensions only

Understand and use vector notation

The notations $\overrightarrow{OA}$ and $\bold{a}$ will be used, as will column vectors

Representation of a vector by a directed line segment

Parallel vectors, unit vectors and position vectors

Sum and difference of two vectors

Modulus (magnitude) of a vector

Multiplication of a vector by a scalar

Find the resultant of two or more vectors

Apply vector methods to simple geometrical problems

The problems may involve colinearity, parallel lines and concurrency

Transformations of the plane

*Reflections in any line

Rotations about any point

Translations

Enlargements*

Combination of transformations

Multiplication of a vector by a matrix

*To include the finding of a matrix for a given transformation of the plane, using

$\begin{pmatrix} 1 \\ 0 \end{pmatrix}$ and $\begin{pmatrix} 0 \\ 1 \end{pmatrix}$

These transformations will be those for which the origin is unchanged*
