Readiness Check

You are ready when you can:

  • Extract period, amplitude, and midline from data/context.
  • Write a sinusoidal model (sine or cosine).
  • Estimate phase from a known point.
  • Predict with domain awareness and rationale.

On the AP Exam

  • MCQ: choose period/amp from a table; pick a reasonable prediction; identify model parameters.
  • FRQ: construct a model; predict; justify with data (skills 1.C, 3.C).

Tactics

1. Mark consecutive max or min; measure horizontal distance for period. 2. Midline $=(\max+\min)/2$; amplitude $=(\max-\min)/2$. 3. Choose sine or cosine based on starting landmark. 4. Plug a known point to find phase. 5. State contextual domain before predicting.

Common Traps

  • Period from peak to trough only.
  • Prediction outside the modeled time window.
  • No rationale for sinusoidal choice.
  • Mixing units (hours vs radians) without consistency.

Quick Checklist

  • [ ] Period from full repeat interval
  • [ ] Amp/midline from max/min
  • [ ] Phase from a known pair
  • [ ] Equation written clearly
  • [ ] Prediction + domain + rationale
