Is y(t-x/v) a Valid Solution to the Wave Equation?

AI Thread Summary
The discussion revolves around understanding whether the function y(t-x/v) is a valid solution to the wave equation. Participants express confusion about the meaning of y(t-x/v) and its relation to the standard wave function y(x,t) = y(x-vt). There is a suggestion to use dimensional analysis to clarify the relationship between the variables. The thread seeks guidance on how to approach the problem without resorting to partial derivatives. Overall, the focus is on clarifying the interpretation and implications of the given function in the context of the wave equation.

Homework Statement



Show that y(t-x/v) is a solution of the wave equation without taking any partial derivatives (hint: use your knowledge about f(x-vt)).


Homework Equations



y(x,t)=y(x-vt)

The Attempt at a Solution



what exactly is y(t-x/v) means, from dimension analysis, its the function of y(t). but how on Earth this relate to y(x,t). rather confused of what this question is asking.

kindly show me how to kick start this.thanks.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
