FIRST ORDER LINEAR DIFFERENTIAL EQUATION: The first order differential equation y0 = f(x,y)isalinear equation if it can be written in the form y0 +p(x)y = q(x) (1) where p and q are continuous functions on some interval I. Differential equations that are not linear are called nonlinear equations. SOLUTION METHOD: Step 1.
