Write down the wave equation for y(x, t). justify your choice of separation constant, show that the general solutions are given by:
vlet cos(kr) 9. sin(kx) cos(kct) sin(ket)

The graph shows the distance y, in inches, a pendulum moves to the right (positive displacement) and to the left (negative displacement), for a given number of seconds x. how many seconds are required for the pendulum to move from its resting position and return? enter your answer in the box.
