This example demonstrates the graph of the cosine function. It involves the core mathematical concept of trigonometric functions. Using GeoGebra commands, we can construct the graph of the cosine function. This example is suitable for high school mathematics education, particularly in coordinate geometry and trigonometry.

GeoGebra Commands & Parameters

  1. Numeric b(-1)
  2. -1 / b
  3. Numeric d(0)
  4. f(x) = cos(x)
  5. Boolean a(false)
  6. Boolean e(false)
  7. g(x) = If[((-3 * π) * abs(b)) + d ≤ x ≤ ((3 * π) * abs(b)) + d, sin((c * (x - d)))]
