The concept of derivatives of trigonometric functions is an essential part of calculus. In this article, we will provide an overview of the derivatives of trigonometric functions, along with examples, solutions, and frequently asked questions. Derivatives of Trigonometric Functions The derivatives of the six trigonometric functions (sine, cosine, tangent, cotangent, secant, and cosecant) can be …
Trigonometric equations are equations that involve trigonometric functions like sine, cosine, tangent, etc. The principal solutions of a trigonometric equation are the solutions that lie within a single period of the function i.e.. 0 to $2\pi$ Principal Solution: The solution in the range $0 \le x \le 2\pi$ How to find the Principal Solutions We can …
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 …

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.
