Waves

Is there any formula for the amplitude of a string fixed at two ends?


@viswaviswa
How are you getting it?

As waves between strings will be sinusoidal, amplitude of string will be sinusoidal and it will be transient ( so we are getting cosine term for 'wt'). There will be no proof for this relation . This is the relation we assume right from the discussion of wave equation

@viswaviswa
can you write the equation again a bit more clearly?
