For a wave to be surfable, it can't break all at once. Robert Guza and Tony Bowen have shown that a wave has a surfable shoulder if it hits the shoreline at an angle 8 given by (ल.गैकाक) 6 = sin (2n + 1) tan(8) where B is the angle at which the beach slopes down and wheren = 0, 1, 2, .. (Round all answers to one decimal place.) For 8 = 25°, find e when n = 4. 0.4
