First-order Ordinary Differential EquationsAdvanced engineering mathematics 1. First-order Basic concepts and ideas Equations3y2+ y-4 = 0 y= ?where yis an unknown. Functionsf(x) = 2x3+ 4x,where xis a variable. Differential equationsA Differential equation is an equation contains one or several derivative of unknown functions (or dependent variables). For example,x= -2 , f(x) = -24x= -1 , f(x) = -6x= 0 , f(x) = 0x= 1 , f(x) = 6: : ( Ordinary Differential equation) (partial Differential equation)Advanced engineering mathematics 1. First-order ODEs3 There are several kinds of Differential Equations An Ordinary Differential equation (ODE) is an equation that contains one independent variable and one or several derivatives of an unknownfunction (or dependent variable), which we call y(x) and we want to determine from the equation.
