Consider the brachistochronie problem of calculus of variations, in which an object is under the effect of the gravitational acceleration g. Recall that the parametric solution of the brachistochrone 9 is I= a[8 – sin), y=a(1. - cos ). (a) The starting point is (0,0) and the end point is 65 1, 1), where they axis is oriented positively downward, as customary for this type of problems. Find, possibly by trial and error, the value of a and the range of for this problem, and sketch the approximate trnjectory in the Cartesian plane (b) Calculate the distance traveled, along the brachistochrone, between these two points. (e) Verify that this distance is longer than the straight line distance (a) Calculate the time to reach the final point, along the brachistochrone. (e) Calculate the time to reach the final point, along the straight lite between the points, and verify that I'l, ie, the travel time along the straight line is longer than along the brachistochrome
