Differential equation is one of the most challenging math courses that you will take when pursuing a civil engineering degree. FIRST ORDERODE: • A first order differential equation is an equation involving the unknown function y, its derivative y' and the variable x. First order differential equations have an applications in Electrical circuits, growth and decay problems, temperature and falling body problems and in many other fields. We then learn about the Euler method for numerically solving a first-order ordinary differential equation (ode). As we have learned in Section 2.5, differential equations are equations that involve “derivatives.” They are used extensively in mathematical modeling of engineering and physical problems. The ﬁrst-order differential equation dy/dx = f(x,y) with initial condition y(x0) = y0 provides the slope f(x 0 ,y 0 ) of the tangent line to the solution curve y = y(x) at the point (x 0 ,y 0 ). Differential equations are of two types for the purpose of this work, namely: Ordinary Differential Equations and Partial Differential Equations. First-Order Differential Equations and Their Applications 5 Example 1.2.1 Showing That a Function Is a Solution Verify that x=3et2 is a solution of the ﬁrst-order differential equation dx dt =2tx. The parameter that will arise from the solution of this first‐order differential equation will be determined by the initial condition v(0) = v 1 (since the sky diver's velocity is v 1 at the moment the parachute opens, and the “clock” is reset to t = 0 at this instant). Then we learn analytical methods for solving separable and linear first-order odes. Differential Equations are extremely helpful to solve complex mathematical problems in almost every domain of Engineering, Science and Mathematics. We introduce differential equations and classify them. In this chapter we illustrate the uses of the linear partial differential equations of first order in several topics of Physics.
