How to get the amplitud , period and those values. And if i have to find the average why and how?
One researcher gathered the following tidal data at Bondi Beach on Monday 24/02/2020 and Tuesday 25/02/2020.
-
(a) Graph the data neatly from the table, giving the tide height h as a function of time t, where time is measured in hours after midnight at the beginning of Monday 24/02/2020. Place an approximate sinusoidal curve through the points.
-
(b) Find a formula y = h(t) = d+A sin [k (t )] which approximately models the tide height, where, as in part a), t is measured in hours after midnight at the beginning of the Monday. For this you will need to caclulate the following (where you may round your calculations to 2 decimal places):
-
(i) An approximation of the amplitude A. Use all values given in the table.
-
(ii) An approximation of the mean value d. Use all values given in the table.
-
(iii) An approximation for the period p, by calculating the time between each successive low tide and then high tide first. Use all values given in the table.
-
(iv) An approximation for the horizontal shift , by using y = h(t) = d + Asin[k(t)] with the values for A, d and p found above and only the first low tide value given.
-
-
(c) Plot or sketch a neat and accurate graph of y = h(t) over the first 24 hours, starting at t = 0. Clearly indicate the maximum and minimum values, as well as the displacement when t = 0.
-
(d) According to the model y = h(t) what is the predicted high tide water depth in the afternoon of Tuesday 03/03/2020?
-
(e) Use the WillyWeather website to find the actual value for the high tide water depth in the afternoon of Tuesday 03/03/2020 and make some brief comment about any differences.
