Explanation The given path y = ( sin x + cos x ) 2 of a bouncing ball can be written as follows. y = sin 2 x + 2 sin x cos x + cos 2 x = 1 + 2 sin x cos x = 1 + sin 2 x [ ∵ sin 2 x = 2 sin x cos x ] Hence, y = ( sin x + cos x ) 2 is written as y = 1 + sin 2 x . Consider y 1 = ( sin x + cos x ) 2 , y 2 = 1 + sin 2 x and y 3 = | sin x + cos x |

(b) Let I[y] be a functional of y(x) defined by [[y] = √(x²y' + 2xyy' + 2xy + y²) dr, subject to boundary conditions y(0) = 0, y(1) = 1. State the Euler-Lagrange equation for finding extreme values of I [y] for this prob- lem. Explain why the function y(x) = x is an extremal, and for this function, show that I = 2. Without doing further calculations, give the values of I for the functions y(x) = x² and y(x) = x³.
