Chapter 7 First-order Differential Equations
www.sjsu.eduFirst order differential equations are the equations that involve highest order derivatives of order one. They are often called “ the 1st order differential equations Examples of first order differential equations: Function σ(x)= the stress in a uni-axial stretched metal rod with tapered cross section (Fig. a),

epsassets.manchester.ac.uk1. Constant coefficient second order linear ODEs We now proceed to study those second order linear equations which have constant coefficients. The general form of such an equation is: a d2y dx2 +b dy dx +cy = f(x) (3) where a,b,c are constants. The homogeneous form of (3) is the case when f(x) ≡ 0: a d2y dx2 +b dy dx +cy = 0 (4)

Differential Equations for Engineers
www.math.hkust.edu.hkThese are second-order differential equations, categorized according to the highest order derivative. The RLC circuit equation (and pendulum equation) is an ordinary differential equation, or ode, and the diffusion equation is a partial differential equation, or pde. An ode is an equation for a function of
