A Study of Differential Equation - A Research Review

This paper is advocated to a general study on differential equation and its type. Differential equations can describe nearly all systems undergoing change. Differential equations are Important in engineering and science branch besides a well as social science and biology and economics etc. they are important in modeling virtually every physical, tech. or biological process from celestial motion to bridge design. This paper also advocates that uses of differential equation in various form. Many fundamental laws in physics and chemistry can be formulated as differential equations. As we know biology and economics, differential equation are used to model the behavior of complex system. Many mathematicians have studied the nature of these equations for hundreds of years and they are many well developed solutions techniques and which are use full for us in present era. My main purpose in this paper is to help the student grasp the nature and significance of differential equations and to this end. So the primary purpose of differential equation is to serve as a tool for the study of change in the physical world. A general book on the subject without a reasonable account of its scientific applications would there for we as futile and pointless. this paper gives the basic and deep knowledge first order differential equation and second order differential equation..
