Lunar Orbit. The motion of a moon moving in a planar orbit about a planet is governed by the equations $\frac{d^{2} x}{{dt}^{2}} = - G \frac{mx}{r^{3}}, \frac{d^{2} y}{{dt}^{2}} = - G \frac{my}{r^{3}}$ where $r = (x^{2} + y^{2})^{\frac{1}{2}}$ , G is the gravitational constant, and m is the mass of the planet. Assume Gm = 1. When $x (0) = 1, x' (0) = y (0) = 0, y' (0) = 1$ the motion is a circular orbit of radius 1 and period $2 π$ .

(a) The setting $x_{1} = x, x_{2} = x', x_{3} = y, x_{4} = y'$ expresses the governing equations as a first-order system in normal form.

(b) Using localid="1664116258849" $h = \frac{2 π}{100} \approx 0.0628318$ ,compute one orbit of this moon (i.e., do N = 100 steps.). Do your approximations agree with the fact that the orbit is a circle of radius 1?

Oscillations and Nonlinear Equations. For the initial value problem $x'' + (0 . 1) (1 - x^{2}) x' + x = 0; x (0) = x_{o}, x' (0) = 0$ using the vectorized Runge–Kutta algorithm with h = 0.02 to illustrate that as t increases from 0 to 20, the solution x exhibits damped oscillations when $x_{o} = 1$ , whereas exhibits expanding oscillations when $x_{o} = 2.1,$ .

In problems 1-6, identify the independent variable, dependent variable, and determine whether the equation is linear or nonlinear.

$y^{3} \frac{d^{2} x}{{dy}^{2}} + 3 x - \frac{8}{y - 1} = 0$

Verify that $ϕ (x) = \frac{2}{(1 - {ce}^{x})},$ where c is an arbitrary constant, it is a one-parameter family of solutions to $\frac{dy}{dx} = \frac{y (y - 2)}{2}$ . Graph the solution curves corresponding to $c = 0, \pm 1, \pm 2$ using the same coordinate axes.

In Problems $15 - 24$ , solve for $Y (s)$ , the Laplace transform of the solution $y (t)$ to the given initial value problem.

$y'' + 3 y = t^{3}; y (0) = 0, y' (0) = 0$
