Class 10th Maths Chapter 8 exercise 8.1

Maths NCERT class 10 ex 8.1 introduces the students to the fundamentals of trigonometry. This exercise majorly concentrates on the basics of trigonometry, which is essential for the upcoming classes. The branch of mathematics in which the heights and angles of a right triangle can be correlated is trigonometry. The word 'trigonometry' is derived from the Greek words 'tri' (meaning three), 'gon' (meaning sides), and 'metron' (meaning measure) justifying its relationship with the three-sided polygon triangle. Class 10th Maths Chapter 8 exercise 8.1 focuses on the trigonometric ratios of the angle. The angles discussed here are predominantly acute angles, for simplicity, though it can be extended to obtuse angles. 

Trigonometry has a lot of real-life applications- it is used in various industries, and even simple distance height problems can be solved with trigonometry. Those types of real-life problem-based questions will also be encountered by the student later in Maths Chapter 8 exercise 8.1.

There are six trigonometric ratios of angle, namely sin, cos, tan, cosec, sec, cot. Of which cosec, sec, and cot are the inverse of sin cos and tan about which you would learn more in detail in Class 10 Maths Chapter 8 exercise 8.1.

In the right triangle, the side opposite to the right angle (i.e., 90 degrees angle) is called the hypotenuse. Let us consider a non-right acute angle of the triangle, say A, and the trigonometric ratios are defined based on the adjacent side of the angle and the opposite side of the angle. The trigonometric ratios are represented as sin A meaning sin of angle A. 

Class 10 Maths ex 8.1 also includes the relationship between the trigonometric ratios of the angle. This is well addressed in the Exercise 8.1 class 10 solutions. Referring to these notes for a better understanding of the relationship between the trigonometric ratios of the angle. Students can also apply it in the right place for easy results. Adopting these techniques can reduce the time consumed to solve a problem significantly, helping students manage time during the examination. 

It is observed in the problems of Class 10 Trigonometry Exercise 8.1 that the values of the trigonometric ratios of an angle do not vary with the lengths of the sides of the triangle if the angle remains the same. In Maths class 10 ex 8.1 solutions, the angles are represented by the Greek letter theta. 

Chapter 8 Maths Class 10 Exercise 8.1 deals with the types of problems like determining the trigonometric ratios given the sides of the triangle, finding the other trigonometric ratios given one of them by constructing a triangle of the respective ratio. Like above-mentioned usage of relations between the trigonometric ratio of the angles can ease the process of solving the problem. Also, operations with the trigonometric ratio might be asked to perform and draw the result values. 

Exercise 8.1 class 10 solutions can be extremely useful when it comes to learning the concepts. The formulas and identities associated with the trigonometric ratios are at their fingertips after referring to these notes and practicing the questions from Exercise 8.1 class 10 solutions Chapter 8 Trigonometry. 

FAQ (Frequently Asked Questions)

1. What are the formulas to calculate the trigonometric ratio of the angles?

Consider a right-angled triangle of an acute angle A

sin A = Side opposite to angle A / Hypotenuse

cos A = Side adjacent to angle A / Hypotenuse

tan A = Side opposite to angle A / Side adjacent to angle A

cosec A = Hypotenuse / Side opposite to angle A

sec A = Hypotenuse / Side adjacent to angle A

cot A = Side adjacent to angle A / Side opposite to angle A 

are the formulas for calculating the trigonometric ratio of the angles.

2. Why is the Class 10 Trigonometry Exercise 8.1 important?

Class 10 Trigonometry Exercise 8.1 covers the fundamentals of the vast branch of mathematics, namely trigonometry. This concept is crucial for understanding the concepts of the student's higher education irrespective of the stream they choose. These concepts are explained and are broken down to their simplest form in Exercise 8.1 Class 10 Maths Ncert solutions. Learning these concepts by heart helps the students score significantly high in their examinations. As the CBSE Board question paper gives a pretty high weightage to this chapter, it's easy to score well once the concepts are well-learned.

3. How Vedantu NCERT solutions help in examination times?
