1. What is a first-order differential equation?
Ans. A first-order differential equation is an equation that involves the first derivative of an unknown function with respect to one independent variable. It can be expressed in the form \( \frac{dy}{dx} = f(x, y) \).
2. How is a first-order differential equation solved?
Ans. First-order differential equations can be solved using various methods such as separation of variables, integrating factors, exact differentials, and substitution techniques.
3. What is the significance of first-order differential equations in real-world applications?
Ans. First-order differential equations are commonly used to model various real-world phenomena such as population growth, radioactive decay, cooling of objects, and chemical reactions. They help in understanding how quantities change over time.
4. Can first-order differential equations have multiple solutions?
Ans. Yes, first-order differential equations can have multiple solutions depending on the initial conditions provided. These solutions can represent different behaviors or trajectories of the system being modeled.
5. How are first-order differential equations relevant to the UPSC exam syllabus?
Ans. Understanding first-order differential equations is essential for candidates preparing for the UPSC exam, especially for subjects like Mathematics, Physics, and Engineering. These equations are often part of the syllabus and can appear in various problem-solving scenarios.
