FAQs on Problems on Trigonometry Video Lecture - Crash Course for SSC CGL (English)
| 1. What is trigonometry? |  |
Ans. Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It involves the study of trigonometric functions such as sine, cosine, and tangent, and their applications in solving various problems involving triangles and periodic phenomena.
| 2. How can trigonometry be used in real-life applications? | |
Ans. Trigonometry has numerous real-life applications. It is used in fields such as engineering, architecture, physics, navigation, astronomy, and even music. For example, architects use trigonometry to calculate angles and distances in order to design structurally sound buildings, while astronomers use it to study celestial bodies and their movements.
| 3. What are the basic trigonometric functions? | |
Ans. The basic trigonometric functions are sine (sin), cosine (cos), and tangent (tan). These functions relate the angles of a right triangle to the ratios of its sides. Sine is the ratio of the length of the side opposite the angle to the hypotenuse, cosine is the ratio of the length of the adjacent side to the hypotenuse, and tangent is the ratio of the length of the opposite side to the adjacent side.
| 4. How do I find the value of trigonometric functions? | |
Ans. The values of trigonometric functions can be found using trigonometric tables or calculators. However, for common angles such as 0°, 30°, 45°, 60°, and 90°, the values of trigonometric functions can be memorized. These values are widely used in trigonometry and can help in quickly solving trigonometric equations or problems.
| 5. Can trigonometry be used to solve non-right triangles? | |
Ans. Yes, trigonometry can be used to solve non-right triangles as well. The Law of Sines and the Law of Cosines are two important formulas used to solve triangles that are not right-angled. The Law of Sines relates the ratios of the lengths of the sides to the sines of the opposite angles, while the Law of Cosines relates the lengths of the sides to the cosine of one of the angles. By using these formulas, the unknown angles and sides of non-right triangles can be determined.
