Chapter 1 First-Order Differential Equations 1.1 Terminology and Separable Equations 1. The differential equation is separable because it can be written 3y 2 dy = 4x, dx or, in differential form, Integrate to obtain 3y 2 dy = 4xdx. y 3 = 2x 2 + k. This implicitly defines a general solution, which can be written explicitly as y = (2x 2 + k) 1/3 , with k an arbitrary constant. 2. Write the differential equation as dy x dx = −y, which separates as 1 1 if x /= 0 an...
