FAQs on Trigonometry: Height & Distance Basic Video Lecture - Crash Course for CAT

1. How to find the height of an object using trigonometry?
Ans. To find the height of an object using trigonometry, you can use the concept of trigonometric ratios. Measure the distance between you and the object, and then measure the angle of elevation from your eye level to the top of the object. By using the tangent function, you can calculate the height as the product of the distance and the tangent of the angle of elevation.
2. How to find the distance between two objects using trigonometry?
Ans. To find the distance between two objects using trigonometry, you can use the concept of trigonometric ratios. Measure the angles of elevation from each object to a common point, and then measure the distance between the two points. By using the tangent function, you can calculate the distance between the two objects as the difference in their distances to the common point divided by the difference in their tangents.
3. What is the angle of depression in trigonometry?
Ans. The angle of depression in trigonometry refers to the angle between a horizontal line and the line of sight when looking downwards from a higher point to a lower point. It is measured below the horizontal line and can be used to calculate distances or heights using trigonometric ratios.
4. How to calculate the angle of elevation using trigonometry?
Ans. To calculate the angle of elevation using trigonometry, you need to measure the distance between you and the object and the height of the object. By using the inverse tangent function, you can calculate the angle of elevation as the inverse tangent of the height divided by the distance.
5. What are the basic trigonometric ratios used in height and distance problems?
Ans. The basic trigonometric ratios used in height and distance problems are sine, cosine, and tangent. In these problems, the sine ratio is used to find the height, the cosine ratio is used to find the distance, and the tangent ratio is used to find both the height and the distance, depending on the given information. These ratios are defined based on the relationships between the sides of a right triangle.
