1. Show that the solution of: 1.1 with initial condition, y(1) = 2 dx is y = V4+ 4x3. 1.2 *+ = sin(2x) with initial condition, = 2 dx is 4xy = sin(2x)- 2x cos(2x) + 2n-1. The deceleration of a certain tugboat in the water is directly proportional to the cube of the speed of the tug at any time t. The velocity of the tug is initially 5 m/s? and reduces to 3 m/s? after 2s. Show that the equation of motion of the tug is 2. 225 by using differential equations. BE+9 业 1.
