Higher Mathematics
Topic practice
Practise Higher Mathematics by section: functions, coordinate geometry, polynomials, calculus, trigonometry, exponentials, logarithms, vectors, recurrence relations and exam-style problem solving.
Composite and inverse functions
Build f(g(x)), reverse simple functions and handle domain restrictions for inverses.
Key skill: Work in the correct order and check the inverse.
Domain, range and transformations
State sensible domains and ranges, then sketch translations, reflections and stretches.
Key skill: Link notation to graph movement.
