Find a solution to the initial value problem y′+sin(t)y=g(t), y(0)=3, that is continuous on the interval [0,2π] where g(t)={sin(t)−sin(t)if 0≤t≤π,if π

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
