Question

A function is represented by equation y=Acoswt cos2wt + Asinwt sin2wt .Then the nature of the function is
a) harmonic
b) non harmonic
c) simple harmonic
d) none of these​

Answer 1

hii dear it's simple Harmonic motion . but of perpendicular .. wave.

y= Acoswt ..

u=Asin(wt- π\2)

Answer 2

Answer:

The nature of the function is called as Simple Harmonic motion.

Explanation:

• A harmonic motion is defined as the motion that oscillates the mass experiences that is when a restoring force will be proportional to the displacement and not in the opposite directions.
• The harmonic motion is called a period and it is represented by the sin wave which has a constant amplitude and a frequency.

Example of harmonic motion:

When a weight starts to bounce on a spring.

It is called as harmonic motion because when something moves it starts to vibrate and causes a sound waves in the air.

• Types of Harmonic motion:

1) Simple Harmonic motion

2) Angular Harmonic motion

Therefore, the function is represented by equation y=Acoswt cos2wt + Asinwt sin2wt .Then the nature of the function will be simple harmonic.
