  4. Today

  5. Recall from Lesson 4.1.3 • What does the “normal” sine graph look like?

  6. Recall from Lesson 4.1.3 What does the “normal” cosine graph look like?

  7. Generating the Sine & Cosine Graph Sine Wave Tracer

  8. Add Sine & Cosine to your Parent Graph Tool Kit Notes • Draw the “normal” graph for each. Label the 5 key points. • Maximum? Minimum? Crossings? • Period? Amplitude? • Parent Equation • General Equation

  9. Sine Graph Period: 2π Amplitude: 1 Maximum: Minimum: Crossings:

  10. Cosine Graph Period: 2π Amplitude: 1 Maximum: Minimum: Crossings:
