Activity 1.8 in Class 10 Science NCERT Book Introduction In this article, we will discuss Activity 1.8 from Chapter 1: Chemical Reactions and Equations in the Class 10 Science ( ncert notes class 10 science ) NCERT textbook. This activity focuses on the fascinating colour change that occurs in silver chloride when exposed to sunlight […]

In this post ,we will see how we can write all the Trigonometric ratios of angle A in the terms of cot A. Here we would be focusing on acute angle A only Value of sin A in terms of cot A From Trigonometric Identity $cosec^2 A = 1 + cot^2 A$or$\frac {1}{\sin^2 A} =

The cosine function, often denoted as cos(x), is a fundamental trigonometric function with a wide range of applications in mathematics, physics, and engineering. In this article, we will specifically discuss the value of the cosine function when its argument is zero, or cos(0), and its significance in various domains. Value of Cos 0 Value of

In this post ,we will see how we can write all the Trigonometric ratios of angle A in the terms of sin A. Here we would be focusing on acute angle A only Value of Cos A in terms of sin A From Trigonometric Identity $\sin ^2 A + \cos ^2 A= 1$or$\cos ^2 A

Prime Numbers

A prime number can be divided, without a remainder, only by itself and by 1. For example, 19 can be divided only by 19 and by 1.

Interesting facts about prime
•The only even prime number is 2. All other even numbers can be divided by 2.
•If the sum of a number’s digits is a multiple of 3, that number can be divided by 3.
•No prime number greater than 5 ends in a 5. Any number greater than 5 that ends in a 5 can be divided by 5.
•Zero and 1 are not considered prime numbers.
•Except for 0 and 1, a number is either a prime number or a composite number. A composite number is defined as any number, greater than 1, that is not prime.
