Robert Guza and Tony Bowen have shown that a wave has a surfable shoulder if it hits the shoreline at an angle 0 given by 9 = sin-1(72n + 1) tan(B)) where B is the angle at which the beach slopes down and where n = 0, 1, 2, .... (Round all answers to one decimal place.) (a) For B = 250, find 0 when n = 2. (b) For B = 150, find 0 when n = 2, 3, and 4. n = 2 n = 3 n = 4 Explain why the formula does not give a value for 0 when n = 0 or 1. O When n = 0 or 1, values are produced that lie outside the domain of sin -1. O The values n = 0 or 1 are not realistic. O When n = 0 or 1, values are produced that lie outside the domain of tan. The values n = 0 or 1 produce denominators that are zero. When n = 0 or 1, values are produced that lie outside the domain of sin. 1 62.F Cloudy Search 7:16 PM 6/11/2023VA 6.5 Homework - MATH 1180, sect X + V X C webassign.net/web/Student/Assignment-Responses/last?dep=31931876#Q2 . ..
