1. A separable differential equation can be written in the form hy) = g(a) where h(y) is a function of y
only, and g(x) is a function of r only.
All of the equations below are separable. Rewrite each of these in the form h(y) = g(x), then find
a general solution by integrating both sides. Determine whether the solutions you found are explicit
(functions) or implicit (curves but not functions)

(b) y' =

(c) y = x(1+ y²)
A circle of radius r centered at the point (0,r) in the plane will intersect the y-axis at the origin and the point A=(0,2r), as pictured below. A line passes through the point A and the point C=(11/2,0) on the x-axis. In this problem, we will investigate the coordinates of the intersection point B between the circle and the
line, as 1 → ∞
