^{Illustrate in graphical terms the relation between a one-one function and its inverse;  sketches should include an indication of the mirror line y = x}
Understand and use the transformations of the graph of
y = f(x) given by
y = f(x) + a, y = f(x + a),
y = af(x), y = f(ax) and simple combinations of these; including use of the terms ‘translation’, ‘reflection’ and ‘stretch’ in describing transformations;  questions may involve algebraic or trigonometric functions, or other graphs with given features.

Review the basic features of sinusoidal functions: midline, amplitude, and period.

Find all the solutions of simple trigonometrical equations lying in a specified interval (general forms of solution are not included),

e.g. solve 3 sin 2x + 1 = 0 
for  ‒π < x < π,
3 sin²θ ‒ 5 cosθ – 1 =0
Use the notations sin^-1x, cos^-1x,  tan^-1x to denote the principal values of the inverse trigonometric relations; no specialised knowledge of these functions is required, but understanding of them as examples of inverse functions is expected.
