Water waves A snapshot of a water wave moving toward shore is described by the function z = 10 sin (2x - 3y), where z is the height of the water surface above (or below) the xy-plane, which is the level of undisturbed water.a. Graph the height function using the window [-5, 5] × [-5, 5] × [-15, 15].b. For what values of x and y is z defined?c. What are the maximum and minimum values of the water height?d. Give a vector in the xy-plane that is orthogonal to the level curves of the crests and troughs of the wave (which is parallel to the direction of wave propagation).
