I really don't understand the concept of differential equations! I'm confused about how you would go about solving them. if (x^2).dy/dx = y^2, integral(y^2)dy = integral(x^2) 1/3y^3 = 1/3x^3 + A ^ What have I done wrong here? I don't get the whole thing where you separate the variables etc. Am I right in saying that integral(dy/dx)dx = y? Moderators, sorry I posted this twice. It was an accident. Please can someone help me understand all of this? I understand basic differentiation and integration.
