## Introduction to Application of Derivatives Class 12 and Rate of Change of Quantities

This section deals with finding the rate at which a quantity changes concerning time. For instance, the velocity of a moving object or the rate of growth of a population.

The Application of Derivatives is a critical concept in mathematics, particularly in calculus. In Class 12, students are introduced to the concept of derivatives and their applications. The Application of Derivatives Class 12 covers various topics, including the rate of change of quantities, increasing and decreasing functions, tangents and normals, approximations, and maxima and minima.

Let’s start by understanding the basics of derivatives. A derivative is a mathematical tool that helps us understand how a function changes over time. In calculus, the derivative of a function represents the rate at which the function changes concerning its input variable. It is denoted by ‘f'(x), where x is the input variable, and ‘f’ represents the function.

The rate of change of quantities is a crucial application of derivatives. This section deals with finding the rate at which a quantity changes concerning time. For instance, the velocity of a moving object or the rate of growth of a population. Let’s take the example of a car moving on a straight road. The velocity of the car is the rate at which the car’s position changes over time. We can find the velocity of the car by taking the derivative of the function representing the car’s position with respect to time.

Another example is the rate of growth of a population. The derivative of the function representing the population with respect to time gives us the rate at which the population is growing or declining.

To calculate the rate of change of quantities, we use the concept of derivatives. The derivative of a function gives us the instantaneous rate of change of the function at a particular point. We can also find the average rate of change of a function over an interval by taking the difference in the function’s values at the endpoints of the interval and dividing it by the length of the interval.

## Increasing and Decreasing Functions

This section helps students determine whether a function is increasing or decreasing in a given interval. It also covers the First Derivative Test, which is used to determine the local maxima and minima of a function.

In the Application of Derivatives Class 12, students learn about increasing and decreasing functions. An increasing function is a function in which the value of the function increases as the input variable increases. Similarly, a decreasing function is a function in which the value of the function decreases as the input variable increases.

To determine whether a function is increasing or decreasing, we use the concept of derivatives. If the derivative of the function is positive, then the function is increasing. On the other hand, if the derivative of the function is negative, then the function is decreasing.

For example, let’s consider the function f(x) = x^2. To determine whether this function is increasing or decreasing, we take the derivative of the function, which is f'(x) = 2x. If the value of x is positive, then f'(x) is positive, which means that the function is increasing. Similarly, if the value of x is negative, then f'(x) is negative, which means that the function is decreasing.

In addition to determining whether a function is increasing or decreasing, we can also find the intervals in which a function is increasing or decreasing. To find the intervals of increase or decrease, we look at the sign of the derivative of the function. If the derivative is positive, then the function is increasing, and if the derivative is negative, then the function is decreasing.

## Tangents and Normals

This section teaches students how to find the equation of a tangent or a normal to a curve at a given point. It also covers the Second Derivative Test, which is used to determine the nature of critical points.

In the Application of Derivatives Class 12, students learn about tangents and normals, which are essential concepts in calculus. A tangent is a straight line that touches a curve at a single point, while a normal is a straight line that is perpendicular to the tangent at the point of contact.

To find the equation of the tangent and normal to a curve at a particular point, we use the concept of derivatives. Let’s consider the curve y = f(x). To find the equation of the tangent at a point (a, f(a)), we first find the derivative of the function, f'(x). We then substitute the value of x as ‘a’ in the derivative, which gives us the slope of the tangent at the point (a, f(a)). The equation of the tangent can be written as y – f(a) = f'(a)(x – a).

To find the equation of the normal at the point (a, f(a)), we first find the negative reciprocal of the slope of the tangent, which gives us the slope of the normal. The equation of the normal can be written as y – f(a) = (-1/f'(a))(x – a).

Using the concept of tangents and normals, we can solve various problems related to optimization, such as finding the maximum or minimum value of a function. To find the maximum or minimum value of a function, we first find the critical points of the function, where the derivative of the function is zero or undefined. We then check whether these critical points are maximum or minimum by analyzing the concavity of the function using the second derivative test. The maximum or minimum value of the function can be found by substituting these critical points back into the function.

## Approximations

This section teaches students how to approximate the values of a function near a particular point using the concept of derivatives.

In the Application of Derivatives Class 12, students learn about approximations, which are useful in various fields, including engineering, physics, and finance. Approximations allow us to estimate the value of a function without knowing its exact value.

One of the most common methods of approximation is a linear approximation. The linear approximation is based on the concept of tangents, which we learned in the previous section. Let’s consider the function f(x) and a point a. The linear approximation of the function at point a can be written as f(x) ≈ f(a) + f'(a)(x-a). This equation gives us an estimate of the value of the function f(x) near point a.

To use the linear approximation, we first find the value of f(a) and f'(a). We then substitute these values in the equation above and estimate the value of f(x) for values of x near a. The accuracy of the linear approximation depends on how close x is to a and the curvature of the function near point a.

Another method of approximation is the use of differentials. Let’s consider the function y = f(x). The differential of y with respect to x can be written as dy/dx. We can use differentials to estimate the change in the value of y when x changes by a small amount. The differential can be written as dy ≈ f'(x)dx. This equation gives us an estimate of the change in the value of y when x changes by a small amount dx.

## Maxima and Minima

This section deals with finding the maximum and minimum values of a function in a given interval. It also covers the concepts of the Absolute Maxima and Minima.

In the Application of Derivatives Class 12, students learn about the concept of maxima and minima, which are critical points of a function that have either the highest or lowest value in a specific interval. The maximum and minimum values of a function are essential in various fields, including economics, physics, and engineering.

To find the maximum or minimum value of a function, we first find the critical points of the function, which are the points where the derivative of the function is zero or undefined. These critical points can be found by setting the derivative of the function equal to zero and solving for x. We then check whether these critical points are maximum or minimum by analyzing the concavity of the function using the second derivative test.

If the second derivative of the function at a critical point is positive, then the critical point is a local minimum, and if the second derivative of the function at a critical point is negative, then the critical point is a local maximum. If the second derivative of the function at a critical point is zero or undefined, then the test is inconclusive, and we need to use other methods to determine whether the critical point is a maximum or minimum.

Once we have found the critical points and determined whether they are maximum or minimum, we can find the maximum or minimum value of the function by substituting these critical points back into the function. The critical point with the highest value of the function is the maximum value, and the critical point with the lowest value of the function is the minimum value.
