what is a good book to learn first order differential equations ??
Differential equations with only first derivatives
A first order differential equation is an equation that involves the first derivative of a function. It is typically in the form of dy/dx = f(x,y), where y is the dependent variable and x is the independent variable.
An ordinary first order differential equation involves only one independent variable, while a partial first order differential equation involves multiple independent variables. This means that in a partial differential equation, the derivative with respect to one variable is taken while holding all other variables constant.
First order differential equations are used in many fields of science and engineering, such as physics, chemistry, biology, and economics. They are commonly used to model and predict the behavior of systems that involve change over time, such as population growth, chemical reactions, and electric circuits.
There are several methods for solving first order differential equations, including separation of variables, integrating factors, and using special substitutions. The specific method used depends on the form of the equation and the initial conditions given.
The initial condition, also known as the initial value, is the value of the dependent variable at a specific point in time or space. It is used to determine the particular solution to the differential equation, as there may be many possible solutions that satisfy the general form of the equation.
