FAQs on Class 10 Maths Chapter 8 Important Question Answers - Introduction to Trigonometry
| 1. What is trigonometry and why is it important in Class 10? |  |
Ans. Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It is important in Class 10 as it forms the foundation for various higher-level concepts in mathematics and physics, and is also relevant in real-life applications such as navigation, engineering, and architecture.
| 2. What are the basic trigonometric ratios? | |
Ans. The basic trigonometric ratios are sine, cosine, and tangent. Sine (sin) is the ratio of the length of the side opposite the angle to the hypotenuse, cosine (cos) is the ratio of the length of the adjacent side to the hypotenuse, and tangent (tan) is the ratio of the length of the opposite side to the adjacent side.
| 3. How do I find the value of trigonometric ratios for specific angles? | |
Ans. To find the value of trigonometric ratios for specific angles, you can use a calculator or reference tables. Simply input the angle in degrees or radians and calculate the corresponding values of sine, cosine, and tangent.
| 4. What is the Pythagorean identity in trigonometry? | |
Ans. The Pythagorean identity in trigonometry is a fundamental equation that relates the three trigonometric ratios (sine, cosine, and tangent) in a right triangle. It states that for any angle in a right triangle, the square of the sine of the angle plus the square of the cosine of the angle is always equal to 1.
| 5. How can trigonometry be applied in real-life situations? | |
Ans. Trigonometry has various real-life applications. For example, it is used in navigation to determine the position and direction of objects, in architecture to calculate angles and dimensions of buildings, in physics to analyze the motion of objects, and in engineering to design structures such as bridges and buildings.
