## FAQs on Differentiation & Integration Video Lecture - Physics for JEE Main & Advanced

 1. What is differentiation and integration?
Ans. Differentiation is a mathematical process that involves finding the rate at which a function changes. It calculates the derivative of a function, which represents the slope of the function at any given point. On the other hand, integration is the reverse process of differentiation. It calculates the area under a curve or the accumulation of a quantity over a given interval.
 2. How is differentiation used in real-life applications?
Ans. Differentiation is widely used in various fields such as physics, engineering, economics, and biology. In physics, it helps determine the velocity and acceleration of objects. In economics, it is used to analyze supply and demand functions. In biology, it is used to model population growth and analyze enzyme reactions. These are just a few examples of how differentiation is applied in real-life situations.
 3. What are the basic rules of differentiation?
Ans. The basic rules of differentiation include the power rule, product rule, quotient rule, and chain rule. The power rule states that the derivative of a function with a constant exponent is equal to the exponent multiplied by the constant coefficient. The product rule is used to differentiate the product of two functions. The quotient rule is used to differentiate the quotient of two functions. The chain rule is used to differentiate composite functions.
 4. How is integration used in real-life applications?
Ans. Integration has numerous applications in various fields. In physics, it is used to calculate the work done by a force, the area under a velocity-time graph, and the displacement of an object. In economics, it is used to calculate the total revenue and total cost functions. In engineering, it is used to calculate the area moment of inertia and the deflection of structures. These are just a few examples of how integration is applied in real-life scenarios.
 5. What are the different methods of integration?
Ans. There are several methods of integration, including substitution, integration by parts, partial fractions, and trigonometric substitution. Substitution involves substituting a variable with a new one to simplify the integral. Integration by parts is used to integrate the product of two functions. Partial fractions are used to break down a rational function into simpler fractions. Trigonometric substitution is used when the integral involves trigonometric functions. These methods provide different approaches to solving integrals based on the nature of the function.
