## FAQs on Fun Video: Overview of Limits and Derivatives Video Lecture - Mathematics (Maths) Class 11 - Commerce

 1. What are limits in calculus?
Ans. Limits in calculus refer to the value that a function approaches as the input approaches a certain point. It helps in understanding the behavior of a function near a particular point without evaluating the function at that point directly. Limits are used to define concepts like continuity, derivatives, and integrals in calculus.
 2. What is the derivative of a function?
Ans. The derivative of a function represents the rate at which the function is changing at any given point. It measures how sensitive the function is to small changes in its input. The derivative is calculated by finding the slope of the tangent line to the graph of the function at a particular point. It helps in analyzing the behavior of the function and is widely used in various fields like physics, economics, and engineering.
 3. How do you find the limit of a function?
Ans. To find the limit of a function, you need to evaluate the function as the input approaches a specific value. There are various methods to find limits, such as direct substitution, factoring, rationalizing, and using special limit theorems like the squeeze theorem or L'Hôpital's rule. The process involves simplifying the expression, plugging in the value, and observing the behavior of the function as it approaches the given point.
 4. What are some common types of limits encountered in calculus?
Ans. In calculus, some common types of limits include: 1. One-sided limits: These limits are approached from either the left or the right side of a point. They determine the behavior of the function as it approaches the point from a specific direction. 2. Infinite limits: These limits occur when the function approaches positive or negative infinity as the input approaches a certain value. They indicate unbounded growth or decay of the function. 3. Composite limits: These limits involve the composition of multiple functions. They require applying limit rules and properties to analyze the behavior of the composite function. 4. Trigonometric limits: These limits involve trigonometric functions like sine, cosine, tangent, etc. They often require the use of trigonometric identities and special limit theorems to evaluate.
 5. How are limits and derivatives related?
Ans. Limits and derivatives are closely related in calculus. The derivative of a function can be defined as the limit of the difference quotient of the function as the change in input approaches zero. In other words, the derivative measures the rate of change of the function at a specific point, which can be interpreted as the slope of the tangent line to the graph of the function at that point. Limits are used in the calculation of derivatives and provide a fundamental concept for understanding the behavior of functions in calculus.
