The Graphical Treatment of Differential Equations

Published online by Cambridge University Press:  03 November 2016

Extract

5. We shall now apply this method to a few typical cases.

(i) The equation y1=x2+y2

gives y2=2x+2y2(x2+y2).

Hence, y1 is always positive; y2 vanishes along the curve

r2=-cot θ,

in which x=r cos θ, y = r sin θ. Hence, in Fig. 5(a), the curves have the form) above the dashed curve (the locus of inflexion), and ( below this curve.
