**How can I get the class 10 introduction to Trigonometry Solutions NCERT?**

First and foremost, Trigonometry is a branch of Mathematics and is also considered as one of the easiest parts of mathematics as said by many experts. There are many ways and means where one can make trigonometry interesting and easy for those who find it difficult to study. These are discussed as follows:

- Let us consider a right-angled triangle. In trigonometry, there are many functions and there are three main functions that one needs to understand. These are:
- sin,
- cos,

From these three basic functions the others can be found out easily like cosec, sec, and cot as these functions are reciprocal to the functions mentioned above respectively.

- One should try to understand the table where the values of sin, cos, tan, cosec, sec, and cot angles are given. For example, in 0 = 0 and many others. Once the students know the values of sin 0, sin 30, sin 45, sin 60, and sin 90 the others can be found out or can be learned easily by knowing an easy trick where one can get the value of the rest easily.
- It is important for one to know the basic three trigonometric formulas that can help one in solving problems easily and quickly.
- It is important for a student to practice the trigonometric numericals on a daily basis with a lot of examples and exercises even if it carries fewer marks say for just around 8 marks as this will not only help the students to score in this chapter but it will help them in the next chapter as well which deals with heights and distances. Moreover, knowing the basics of this subject will also be helpful in the long run for other competitive examinations as well as entrances.
- Trigonometry is not a chapter to be learned only in school but students need to be clear with the basics as in higher classes students will learn more about trigonometry for example inverse trigonometry.

In order to score well and to master Trigonometry, daily and consistent practicing is needed from the students so that it will be easier for them in answering and solving questions and problems that come in the examination. A proper schedule should be made in order to complete the syllabus in time. The students must first complete the whole NCERT textbook of Mathematics which has the trigonometry part and then try to practice questions from reference books and guide books to enhance their knowledge and to check their understanding level. On top of teachers’ lectures and notes, the students should give more time to it and they can also learn more by taking advantage of the online platforms by downloading study materials and also by checking out explanations in youtube videos. Good videos can be selected by checking and seeing the reviews on the video as well as the number of views. This will help one understand visually and also help in understanding the formulas, their derivations as well as the applications in a better way. After the student is confident with his/her preparation from the NCERT textbook then he/she can pick up a reference book suggested by his/her teachers.

Also, students need to memorize the formulae which will really help them in solving questions without wasting their time in remembering or deriving the formulae. The students need to practice more and more problems of trigonometry so that they will be able to manage and monitor the time. Old question papers can also be a good source of understanding how questions are being set for the examination and for students to check their preparation level. The most important part of trigonometry is for one to be clear with his/her doubts. It is also important for the students to understand which formula to apply for which problem that comes during the examination without having to think much. This will automatically come only with a constant practice of the numerical on a daily basis.

**Do you know the answer of the below question?**

**Q: **If cos A=4/5, then the value of tanA is** **

- A) 3/5
- B) 3/4
- C) 4/3
- D) 5/3

Hence, the students need to practice more and more in order to master the technique of problem-solving. All the questions from the NCERT textbook need to be solved with a proper understanding of the various concepts and formulae so that whatever problem comes the students will be able to solve. Students can practice and solve problems from the R.D. Sharma textbooks also, as this book contains some important questions that used to come in the examination if not all. First, of all try to understand the problems, practice the sums by copying, so as to know the steps to be followed for solving. It is important to understand some tricks as well in problem-solving and to be able to do it on their own.
