Here starting with a general introduction, distance formula, section formula, area of the triangle are a few topics covered in this chapter followed with examples and exercises for better and thorough practice purposes.

**Chapter-8Â Introduction to Trigonometry**

As trigonometry is a very important and vast subject, this topic is divided into two parts where one chapter is Introduction to Trigonometry and another part is Applications of Trigonometry. This Introduction to Trigonometry chapter is started with a general introduction, trigonometric ratios, trigonometric ratios of some specific angles, trigonometric ratios of complementary angles, trigonometric identities, etc are a few important topics covered in this chapter.

**Chapter-9Â Applications of Trigonometry**

This chapter is the continuation of the previous chapter, where the various modeled applications are discussed here with examples and exercises for better understanding. Topics like heights and distances are covered here and at the end, a summary is provided with all the important and frequently used formulas used in this chapter for solving the problems.

**Chapter-10Â Circle**

Beginning with the introduction to circles, tangent to a circle, several tangents from a point on a circle are some of the important topics covered in this chapter. This chapter being practical, there are an ample number of problems and solved examples for better understanding and practice purposes.

**Chapter-11Â Constructions**

This chapter has more practical problems than theory-based definitions. Beginning with a general introduction to constructions, tools used, etc, the topics like division of a line segment, construction of tangents to a circle, and followed with few solved examples that help in solving the exercises provided after each topic.

**Chapter-12Â Areas related to Circles**

This chapter problem is exclusively formula based wherein topics like perimeter and area of a circle- A Review, areas of sector and segment of a circle, areas of combinations of plane figures, and a page summary is provided just as a revision of the topics and formulas covered in the entire chapter and also there are many exercises and solved examples for practice purposes.

**Chapter-13Â Surface Areas and Volumes**

Starting with the introduction, the surface area of a combination of solids, the volume of a combination of solids, conversion of solid from one shape to another, frustum of a cone, etc are to name a few topics explained in detail provided with a set of examples for a better comprehension of the concepts.

**Chapter-14Â Statistics**

In this chapter starting with an introduction, topics like mean of grouped data, mode of grouped data, a median of grouped, graphical representation of cumulative frequency distribution are explained in detail with exercises for practice purposes. This chapter being a simple and easy subject, securing the marks is not difficult for students.

**Chapter-15Â Probability**

Probability is another simple and important chapter in examination point of view and as seeking knowledge purposes as well. Beginning with an introduction to probability, an important topic called A theoretical approach is explained here. Since this chapter is one of the smallest in the syllabus and problems are also quite easy, students often like this chapter.

Trignometric ratios are the ratios of different sides of a right angled triangle with respect to an angle. At the end of this session, you will be able to find the height of theÂ pedestal using some trignometric ratios.

Please watch the entire video lecture for a better understanding of this key topic of CBSE Class 12 Math/ NCERT Class Maths. In this video you will learn how to calculate the Area of a Quadrant which is one quarter of a full circle.

An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant which is represented by ‘d’. In the sequence in this video, with the first few terms given and by using two consecutive terms, we can find the common difference (which is equals to the difference of two consecutive terms).

In this video, we will use the method of cross-multiplication to find out the values of the x and y variables. Students are advised to go through the entire video to get in-depth understanding of the topic.

In the question explained in this video, the maximum value of relative humidity (in percent) is 99.2% and the smallest value is 84.9%. So, to find out the range of the given data, we need to substract the maximum value with minimum value.
