This example demonstrates how a simple engine's reciprocating motion generates a sinusoidal wave. It involves core math concepts like Sine, Cosine, and Trigonometry. Construction highlights include commands like Circle, Rotate, Segment, Angle, If, and Polygon, utilizing objects such as r, A, o, t, P, etc. Ideal for high school students studying trigonometric functions, coordinate geometry, and physics vibrations.

GeoGebra Commands & Parameters

  1. Circle(A, r) → o
  2. Rotate(P, t, A) → B
  3. Segment(A, B) → c
  4. Angle(c, yAxis) → α
  5. Angle(P, A, B) → Θ
  6. If(sin(α) ≟ 0, a + (sin(Θ) * c), (a * sin(β) / sin(α))) → b
  7. Segment(B, C) → d
  8. Polygon(D, E, G, F) → poly1, d_1, e, g, f
