Program Explanation Given information: The value of a is 100 mi , the speed of plane relative to wind is v 0 = 400 mi / h and the speed of wind is w = 40 mi / h . The solution of differential equation that satisfies the equation of plane trajectory is, y ( x ) = a 2 [ ( x a ) 1 − k − ( x a ) 1 + k ] ....... (1) Explanation: The value of constant k is, k = w v o = 40 400 = 1 10 Substitute 100 for a and 1 10 for k in equation (1). y ( x ) = 100 2 [ ( x 100 ) 1 − 1 10 − ( x 100 ) 1 + 1 10 ] = 50 [ ( x 100 ) 9 10 − ( x 100 ) 11 10 ] = 50 [ x 9 10 100 9 10 − x 11 10 100 11 10 ] Differentiate the above equation with respect to x . d y d x = 50 [ 9 10 ⋅ 100 9 10 x 9 10 − 1 − 11 10 ⋅ 100 11 10 x 11 10 − 1 ] = 50 [ 9 10 ⋅ 1 100 ⋅ 100 − 1 10 ⋅ x − 1 10 − 11 10 ⋅ 1 100 ⋅ 100 1 10 ⋅ x<
