Homework Statement
(a) Write the expression for y as a function of x and t in SI units for a sinusoidal wave traveling along a rope in the negative x direction with the following characteristics: A = 5.00 cm, λ =85.0 cm, f = 5.00 Hz, and y(0, t) = 0 at t = 0. (Use the following as necessary: x and t.)
Write the expression for y as a function of x and t for the wave in part (a) assuming y(x, 0) = 0 at the point x = 17.0 cm. (Use the following as necessary: x and t.)
Homework Equations
Conversion equations from f and lambda to k and omega
y(x,t) = Asin(kx(+/-)wt)
The Attempt at a Solution
$$5\sin \left(10\pi t+\frac{2}{85}\pi x-.4\pi \right)$$
Why is this wrong? I don't understand. I put it into desmos, and it shows AT LEAST that at at y(17,0) = 0. Also based off the slider, it seems to be going in the negative x-direction, which is correct.
