Question

List three real-world examples that can be modeled with a sinusoidal function.

Answer 1

1.The periodic rotations of a crankshaft in an engine.

2. The rotation of a Ferris wheel.

3. The fluctuating hours of daylight in a specific location throughout a calendar year

below is proof

Answer 2

A sinusoidal function is like a sine function and it has few real life usages.

Explanation:

1.The periodic rotations of a crankshaft in an engine.

2. The rotation of a Ferris wheel.

3. The fluctuating hours of daylight in a specific location throughout a calendar year

The sinusoidal wave is a curve that describes a smooth repetitive oscillation. In these 3 examples, we can plot the movement of the object in a graph paper and we will see a sine wave. That's why these are the real life example of sinusoidal wave.
