ZERO  Before the invention of zero by Aryabhata, numerical systems primarily relied on positional notation, where the position of a digit determines its value. However, the absence of zero posed some challenges in representing numbers. In ancient numeral systems, such as the Roman and Egyptian systems, there was no dedicated symbol for zero. Instead, these systems relied on omission to represent zero. For example, in the Roman numeral system, which was widely used in the Western world, the number 10 was represented by the symbol 'X,' while the number 100 was represented by the symbol 'C.' To represent numbers that were smaller than these, additional symbols were used, such as 'I' for 1 and 'V' for 5 and 'X' for 10 etc.... Aryabhata, an Indian mathematician and astronomer,invented the concept of zero as a numeral in the 5th century. He used a dot underneath numbers to represent zero. This revolutionary idea of zero as a placeholder allowed fo...

  IS IT POSSIBLE THAT 1 EQUAL TO -1  can we prove 1=-1 .. is it possible to write -1=1 ? mathematics puzzles. mathematics formula confusion. DOES MATHS FAILS??? MATHS IN YOUTUBE IS IT POSSIBLE? AWESOME MATHS INTERESTING QUESTIONS. #mathstricks #mathsfails #confusingQuestion #isitpossible No, it is not possible for one to be equal to minus one. In mathematics, the numbers one and minus one (-1) are distinct and have different values. The number one (1) represents a positive quantity, whereas minus one (-1) represents a negative quantity. They are located on opposite sides of zero on the number line and have different magnitudes. Mathematically, the equation "1 = -1" is not true and does not hold under the standard rules of arithmetic. If we try to solve it, we can see that it leads to a contradiction: If we multiply both sides of the equation by one, we get: 1 * 1 = 1 * (-1) Which simplifies to: 1 = -1 However, this is not possible because one and minus one are differen...

TRIGONOMETRIC IDENTITY  A trigonometric identity is an equation involving trigonometric functions that holds true for all values of the variables within its domain. There are several fundamental trigonometric identities that are widely used in mathematics. Here are some of the most common ones: Pythagorean Identity: sin^2(x) + cos^2(x) = 1 This identity relates the values of sine and cosine for any angle x in a right triangle. Reciprocal Identity: csc(x) = 1/sin(x) sec(x) = 1/cos(x) cot(x) = 1/tan(x) These identities express the reciprocals of sine, cosine, and tangent in terms of the corresponding trigonometric functions. Quotient Identity: tan(x) = sin(x)/cos(x) cot(x) = cos(x)/sin(x) These identities express tangent and cotangent in terms of sine and cosine. Co-Function Identities: sin(pi/2 - x) = cos(x) cos(pi/2 - x) = sin(x) tan(pi/2 - x) = cot(x) cot(pi/2 - x) = tan(x) These identities relate the values of trigonometric functions for complementary angles. Even-Odd Identities:...

  ZERO - EVEN OR ODD Zero is an even number. In mathematics, an even number is defined as any integer that is evenly divisible by 2, meaning there is no remainder when dividing it by 2. Since zero can be divided by 2 without any remainder (0 ÷ 2 = 0), it is considered an even number. FOR VIDEO SOLUTION ------ CLICK HERE Zero is an even number. An even number is defined as any integer that is divisible by 2, with zero being evenly divisible by 2. Therefore, zero meets the criteria of being an even number . 3 / 3 Zero is considered an even number. An even number is any integer that is divisible by 2 without leaving a remainder. Since zero can be divided by 2 without a remainder (0 ÷ 2 = 0), it falls into the category of even numbers. HENCE ,  Zero is an even number. An even number is defined as any integer that is evenly divisible by 2, meaning it can be divided by 2 without leaving a remainder. Since zero divided by 2 equals zero with no remainder, it satisfies the condition...
