In summary, The conversation is about solving a problem by eliminating the unknown amplitude and angular frequency. One person is trying to explain their attempt, but the other person cannot understand it because it is not typed out. The solution involves using sin2(ωt)+cos2(ωt)=1 and eliminating the amplitude and angular frequency separately.

Disregard the tangent stuff on the right I tried doing something else...

Any clues?

I would be able to read your attempt if it was typed in.
Such problems are solved by eliminating the unknown amplitude by using sin2(ωt)+cos2(ωt)=1

By the way, you weren't to see my pictures? Mhm.

You are supposed to type in your work. I can not decipher what you did from the pictures.

Do the same you did when eliminating the amplitude, but eliminate omega this time.

It is x=Asin(wt) and dx/dt= Aw cos (wt). The displacements and speeds are given at two different times.

a=A sin(wt1) u/w=Acos(wt1) -->a2+( u/w)2=A2

b=Asin(wt2) v/w=A cos(wt2) -->b2+( v/w)2=A2


Eliminate the angular frequency this time.

FAQ: How can angular frequency be eliminated in solving a challenging SHM problem?

What is SHM and why is it important?

SHM stands for Simple Harmonic Motion and it refers to the back-and-forth motion of an object around an equilibrium point. This type of motion is important because it can be observed in many natural phenomena and has many practical applications, such as in the design of pendulum clocks and tuning musical instruments.

What are some common challenging problems in SHM?

Some common challenging problems in SHM include calculating the period and frequency of an oscillating object, determining the amplitude and displacement of the motion, and analyzing the effects of damping on the system.

How can SHM be applied in real-world situations?

SHM has many practical applications, such as in the design of suspension systems for vehicles, earthquake-resistant buildings, and shock absorbers for machinery. It is also used in fields like seismology, acoustics, and optics.

What are some techniques for solving challenging SHM problems?

Some techniques for solving challenging SHM problems include using differential equations, vector analysis, and energy conservation principles. Graphical analysis and computer simulations can also be helpful in understanding and solving these problems.

How can understanding SHM contribute to advancements in other areas of science?

Understanding SHM is essential in many areas of science, such as physics, engineering, and mathematics. It provides a basis for understanding more complex systems and phenomena, such as waves, vibrations, and resonance. This knowledge can then be applied to develop new technologies and improve existing ones.
