This individual framework pack gives you one
complete, focused topic framework for your
IB Math AA Internal Assessment.
THE FRAMEWORK: Trigonometric Applications
This framework guides you through an investigation
using trigonometric functions to model, analyse,
or solve a real-world problem involving periodic
behaviour, angles, or wave-like patterns.
MATHEMATICAL CONCEPTS:
✓ Sine, cosine, and tangent functions
✓ Sine rule and cosine rule
✓ Trigonometric identities
✓ Sinusoidal modelling
✓ Period, amplitude, and phase shift
✓ Non-right-angled triangle problems
SL APPROACH:
Model a periodic or angular real-world phenomenon
using trigonometric functions. Focus on clear
application and interpretation of results.
HL APPROACH:
Extend to composite trigonometric functions,
identities-based proofs, or inverse trigonometric
applications for greater depth.
PERSONALIZATION OPTIONS:
â–¡ Tidal patterns and ocean behaviour
â–¡ Sound waves and music frequency
â–¡ Seasonal temperature cycles
â–¡ Ferris wheel or pendulum motion
â–¡ Shadow length and sun angle analysis
â–¡ Your own periodic or angular phenomenon
