Let A(x) and B(x) be polynomials (with coefficients in R). We say that ged(A(x), B(x)) = D(x) if D(x) divides A(x) and B(x), and if every polynomial C(x) that divides both A(x) and B(x) also divides D(x). For example, gcd((x - 1)(x + 1), (x - 1)(x+2)) = x – 1. Notice this is the exact same as the normal definition of GCD, just extended to polynomials.
Incidentally, gcd(A(x),B(x)) is the highest degree polynomial that divides both A(x) and B(x). In the subproblems below, you may assume you already have a subroutine divide(P(x),S(x)) for dividing two polynomials, which returns a tuple (Q(x),R(x)) of the quotient and the remainder, respectively, of dividing P(x) by S(x). (a) Write a recursive program to compute gcd(A(x),B(x))
Write a recursive program to compute god(A(x), B(x)).

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
