Use your knowledge of second-order systems forced by a sinusoidal function to solve (a) y '''' + y ′′ = sin x.

Hint: Try to integrate twice immediately. Extra hint: Your solution should involve four constants.

(b) Instead consider y'''' + y ′′ = x sin x. Note that ∫ x s sin s s = sin x − x cos x + c, where c is a constant.

(a)Use Netwons Second Law of Motion to prove that the equation governing the forced damped harmonic oscillator (spring-mass system) is: mx"(t) + cx'(t) + kx(t) = F(t): (Explain what the constants m; c; k are and what the function F(t) is. Draw a picture of the system.) (b)Assume m = 1; c = 0; k = 4; that F(t) = cos(2t); and that the object attached to the spring begins from the rest position. Find the position function using the...
