Question: (a) A simple model for the shape of a tsunami is given by dW /dx = W ( 4 ? 2W ), where W(x) >
(a) A simple model for the shape of a tsunami is given by dW /dx = W
( 4 ? 2W ), where W(x) > 0 is the height of the wave expressed as a function of its position relative to a point offshore. By inspection, find all constant solutions of the DE. (Enter your answers as a comma-separated list.) W = ?
(b) Solve the differential equation in part (a). A CAS may be useful for integration. W(x) = ?
(c) Use a graphing utility to obtain the graphs of all solutions that satisfy the initial condition W(0) = 2.
