You will learn the application of derivatives, finding rate of change, show increasing/decreasing in whole domain, in intervals, find intervals of increasing/decreasing, Rolle’s theorem, Lagrange’s Mean Value theorem, finding slope of tangent/normal, point when tangent is parallel/ perpendicular, when point and curve is known, when slope and curve are known, approximate value of numbers, function, minimum and maximum values from graph, local maxima and minima, absolute minima/maxima.

In NCERT solutions for class 12 maths chapter 6 you will learn the rate of change of quantities, increasing and decreasing functions, tangents, and normals, Rolle’s theorem, Lagrange’s Mean Value theorem, approximations, maxima, and minima. Let us now discuss the subtopics include in this chapter.In this section, you will learn how the derivatives of number and functions are applied and used.

## Rate of Change of Quantities

In this, you will study the change of quantity with respect to another quantity by some rules, change of two quantities with respect to another quantity by the chain rule.

## Increasing and Decreasing Functions

In this you will study about whether the function is increasing, strictly increasing, decreasing, or strictly decreasing.

## Tangents and Normals

In this section, you will learn to use differentiation to find the equation of the tangent line and the normal line to a curve at a given point, different cases, Rolle’s Theorem, Lagrange’s Mean Value Theorem

## Approximations

In this, you will learn to use differentials to approximate values of certain quantities.

## Maxima and Minima

In this, you will learn to use the concept of derivatives to calculate the maximum or minimum values of a function, points of local maxima and minima, first derivative test, second derivative test.

• Maximum and Minimum Values in a Function in a Closed Interval

In this, you will learn to find the absolute maxima, absolute minima of a function in a closed function.
