The motion of n planets (Po, P₁,..., Pn-1) is governed by the set of 6n first order ODEsnr₁ = V₁_and_vi' = Σ Gm;j=1jirj - rid¾3(5.10)where mi, ri(t) and vi(t) are the mass, position vector and velocity of the planet Pi, respectively.The scalar dij = dji = ||r¡—ri|| is the distance between the two planets Pi and Pj. The gravitationalconstant, G, can be taken equal to 1 without loss of generality.

Let l be a line in the x-yplane. If l is a vertical line, its equation is x = a for some real number a. Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept. If l passes through the point (x₀, y₀), the equation of l can be written as y - y₀ = m(x - x₀). If (x₁, y₁) and (x₂, y₂) are two points in the x-y plane and x₁ ≠ x₂, the slope of line passing through these points is m = (y₂ - y₁)/(x₂ - x₁). Instructions Write a program that prompts the user for two points in the x-y plane. Input should be entered in the following order: Input x₁ Input y₁ Input x₂
Given is a strictly increasing function, f(x). Strictly increasing meaning: f(x)< f(x+1). (Refer to the example graph of functions for a visualization.) Now, define an algorithm that finds the smallest positive integer, n, at which the function, f(n), becomes positive. The things left to do is to: Describe the algorithm you came up with and make it O(log n).

Computer Science Think you are given a point A (2, 7). First apply a translation (-n, -m) then shear by (3/2, -3) and finally apply again a translation (m, n). What will be the final coordinates of that point? Here m=3, n=6.
