### Arithmetic Progressions of exercise 5.1 *(Class 10 Maths exercise 5.2)* you have studied the following points:

- An arithmetic progression (AP) is a list of numbers in which each term is obtained by

adding a fixed number d to the preceding term, except the first term. The fixed number d

is called the common difference.

The general form of an AP is a, a + d, a + 2d, a + 3d, . . . - In an AP with first term a and common difference d, the nth term (or the general term) is

given by an= a + (n – 1) d. - The sum of the first n terms of an AP is given by : S=n/2[2a+(n-1)d].
- If l is the last term of the finite AP, say the nth term, then the sum of all terms of the AP

is given by : S=n/2(a + l). - If a, b, c are in AP, then b=(a + b)/2 and b is called the arithmetic mean of a and c.

**NCERT Solutions for Class 10 Maths Chapter 9 Some Applications of Trigonometry of exercises 9.1 **for all boards. We have updated all the contents for the new academic session 2020-2021.

In this chapter, you have studied the following points:

- The line of sight is the line drawn from the point of view of the observer to the object seen by the observer.

- The angle of elevation of the observed object is the angle formed by the line of sight with the horizontal level when it is above the horizontal level, that is, when we raise our head to see the object.
- The angle of depression of an object is seen as the angle formed by the line of sight with the horizontal level when it is below the horizontal level, that is, when we lower our head to see the object.
- The height or length of an object or the distance between two distant objects can be determined with the help of trigonometric ratios.
