You know how to reflect a graph in the coordinate axes, but what about in x = a or y = a? Reflections in y = a (y = 2a − f(x)) and in x = a (y = f(2a − x)) from first principles, how to express reflection symmetry algebraically, and using a reflection to simplify a definite integral. Then four questions from TMUA and the JZMaths mock papers, connecting these ideas with trigonometric graphs, necessary and sufficient conditions, and integration.
