Real-World Applications of Trigonometric Functions: Introduction
In this section, you will see how the trigonometric functions are used in real-world situations. Sinusoidal functions are any functions of the form f(x) = Asin(kx - c) + h or f(x) = Acos(kx - c) + h. These sinusoidal functions are used in many different areas, including:
- Physics, such as pendulum and swinging motions
- The tides of oceans
- Blood pressure in the heart
- Population planning
- Piston-crankshaft movement
- Hours of daylight
- Climate and seasons
- Behavior of sound
