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

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

Step-by-step 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.

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

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
