Wave and oscillation

see attached file it's very helpful for you dear

see attached file

Actually cos(wt) and sin(wt) are not different, they have just a phase difference of π/2. They both can be the solution of a given equation. just the phi will change, rest will rem...

thanks all of u

now I understood

by putting value of x , we get a negative sign. so I confused

see attached I gave explanation for both displacement and the velocity of the oscillator.

you can take either! It's totally dependent on initial conditions. if initially partycal is at extream position, then it should be cos(wt) , because cos(0) = 1, but if initially it...

ans to your question.
