Linearization around that point gives that approximately at infinity y ″ = y. The stable solution satisfies y ′ = − y, which would also give a more realistic right boundary condition. In this case one can integrate once to y ′ 2 = 2 cosh ( y) + C.

The main idea comes from the intermediate value theorem: If f(a) and f(b) have different signs and f is continuous, then f must have a zero between a and b. We evaluate the function at the midpoint, c = 1 2(a + b). f(c) is either zero, has the same sign as f(a) or the same sign as f(b).
