Identities, Equations, Applications

Trigonometry appears everywhere in senior mathematics — in calculus, coordinate geometry, complex numbers and vectors. Students who are fluent with identities and the behaviour of trigonometric functions save time across the whole syllabus.

We build that fluency through understanding, not memorisation: seeing why identities hold, recognising which one a problem needs and practising until the choice becomes natural.

Highlights

  • Radian measure and trigonometric functions
  • Identities, and how to choose the right one
  • Trigonometric equations
  • Inverse trigonometric functions
