In the ch 9 Maths class 10, we will be learning about trigonometry, some application of trigonometry, and the entire summary of the chapter. What is Trigonometry? Trigonometry is one of the most historical subjects studied by different scholars throughout the world. As you have read in Chapter 8 that trigonometry was introduced because its requirement arose to astronomy. Since then trigonometry is used to calculate the distance from the Earth to the stars and the planets.

The most important use of trigonometry is to find out the height of the highest mountain in the world i. Mount Everest which is named after Sir George Everest. It is also widely used in Geography and navigation. The knowledge of trigonometry enables us to construct maps, evaluate the position of an island concerning the longitudes and latitudes. Historical Facts. Let us Turn to the History of Trigonometry. The trigonometry was used by surveyors for centuries.

The highest mountain in the world was discovered during the survey in From a distance of over km, this peak was seen from 6 distinct stations. This peak was named after Sir George Everest who had first used the theodolites. Theodolites are now exhibited in the museum of the surveys of Dehradun.

Surveying instrument, which is used for measuring angles with a rotating telescope. Height and Distance. In this topic, you will study about the line of sight, angle of elevation, horizontal level, and angle of depression. All these terms are explained in a detailed form along with some solved examples based on it.

These solved examples based on the terms line of sight, angle of elevation and angle of depression will help you to understand the concepts thoroughly. How to Calculate Height and Distance? Trigonometric ratios are used to find out the height and the distance of the object. For example: In figure 1, you can see a boy looking at the top of the lampost.

AB is considered as the horizontal level. This level is stated as the line parallel to the ground passing through the viewer's eyes. AC is considered as the line of sight. An inclinometer or Clinometer is a device usually used for measuring the angle of elevation and the angle of depression.

Let us recall some trigonometric ratios which help to solve the questions based on class 10 maths Chapter 9. Trigonometry Ratios.

The ratio of the sides of a right-angle triangle in terms of any of its acute angle triangle is known as the trigonometric ratio of that specific angle. Sine - The sine of an angle is stated as the ratio of the opposite side perpendicular side to that angle to the hypotenuse side. Cosine- The cosine of an angle is stated as the ratio of the adjacent side to that angle to the hypotenuse side. Tangent - The tan of an angle is stated as the ratio of the opposite side perpendicular side to that angle to the side adjacent to that angle.

Cosecant- It is the reciprocal of sine. Secant- It is the reciprocal of cosine. Cotangent- It is the reciprocal of tangent. The following trigonometry ratio table is used to calculate the questions based on applications of trigonometry class 10 NCERT solutions. Sin C. Cos C. Tan C. Not defined.

Cosc C. Sec C. Cot C. Now, you must have understood all the important topics and terms covered in each section of class 10 maths chapter 9.
