Trigonometric functions study repeating patterns and oscillation.
They became essential for physics, engineering, and wave systems.
What This Topic Studies
This section studies:
- sine functions
- cosine functions
- tangent functions
- periodic behavior
These functions model repeating systems.
Why Humans Invented Trigonometric Functions
Astronomy, sound, and physics required mathematics for studying:
- waves
- rotation
- vibration
- periodic motion
Trigonometric functions gradually became tools for modeling these systems.
Main Mathematical Ideas Introduced
This section introduces:
- periodic graphs
