# NCERT Solutions Class 12 Maths Chapter 6 Application of Derivatives

NCERT Solutions for Class 12 Maths Chapter 6 Application of Derivatives explains the fundamental concepts and Application of Derivatives in different disciplines. The Application of Derivatives is widely found in the field of engineering, science, economics, social science, etc. When it comes to studying the various aspects of physics or engineering even the slightest miscalculation can result in huge errors. Thus, it is highly important for kids to form a firm base to apply the knowledge of derivatives and related concepts in real life. In this chapter, we will learn how the derivative can be used to determine the rate of change of quantities. It also talks about how derivatives are applied to find extreme values of functions, to determine and analyze the shapes of graphs, and to solve equations numerically.

One of the most important Application of Derivatives is to find the optimal solution to problems. For example, to find the equations of tangent and normal to a curve at a point or to find turning points on the graph of a function which in turn will help us to locate points at which the largest or smallest value (locally) of a function occurs. Derivatives are also useful in calculating the intervals on which a function is increasing or decreasing. Lastly, it is also helpful to find the approximate value of specific quantities. NCERT Solutions Class 12 Maths Chapter 6 enhances the fundamental understanding of students about the Application of Derivatives. With the regular practice of Class 12 Maths NCERT Solutions Chapter 6, students will quickly gain a deep understanding of this topic.

## List of Formulas in NCERT Solutions Class 12 Maths Chapter 6

The Application of Derivatives is considered as one of the basic topics in learning calculus that is especially useful in optimizing the solutions of various problems. Understanding these applications requires knowledge of the rules and concepts applied in derivatives. Most of the questions require kids to employ their mathematical acumen to understand what needs to be done. As the techniques and formulas used to solve textbook sums are also utilized for combating real-life issues students must be well-versed in them. Thus NCERT Solutions Class 12 Maths Chapter 6 elaborates each of these concepts using examples some of which are given below:

- If a quantity y varies with another quantity x, satisfying some rule y = f(x), then dy/dx (or f′(x) ) represents the rate of change of y with respect to x and dy/dx
_{ x = x0}( or f′( x_{ 0}) ) represents the rate of change of y with respect to x at x = x_{ 0}.

- A function f is said to be increasing on an interval
- (a, b) if x
_{1}< x_{2}in (a, b) ⇒ f(x_{1}) < f(x_{2}) for all x_{1}, x_{2}∈ (a, b) - Decreasing on (a,b) if x
_{1}< x_{2}in (a, b) ⇒ f( x_{1}) > f (x_{2}) for all x_{1 }, x_{2}∈ (a, b) - Constant in (a, b), if f (x) = c for all x ∈ (a, b), where c is a constant.

- In calculus, a derivative test uses the derivatives of a function to locate the critical points of a function and determine whether each point is a local maximum, a local minimum, or a saddle point. Derivative tests can also give information about the concavity of a function.

**a) First Derivative Test**: The first derivative test is applied to analyze the functions using their first derivatives in order to find their extremum point.**b) Second Derivative Test**: The Second Order Derivative is the derivative of the first derivative of the given function.
