  3. Irrational number - Wikipedia

    en.wikipedia.org/wiki/Irrational_number

    Among irrational numbers are the ratio π of a circle's circumference to its diameter, Euler's number e, the golden ratio φ, and the square root of two. [1] In fact, all square roots of natural numbers, other than of perfect squares, are irrational. [2] Like all real numbers, irrational numbers can be expressed in positional notation, notably ...

  4. Methods of computing square roots - Wikipedia

    en.wikipedia.org/wiki/Methods_of_computing...

    A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...

  6. Square root - Wikipedia

    en.wikipedia.org/wiki/Square_root

    (See square root of 2 for proofs that this is an irrational number, and quadratic irrational for a proof for all non-square natural numbers.) The square root function maps rational numbers into algebraic numbers , the latter being a superset of the rational numbers).

  7. Rational number - Wikipedia

    en.wikipedia.org/wiki/Rational_number

    A real number that is not rational is called irrational. [5] Irrational numbers include the square root of 2 (⁠ ⁠), π, e, and the golden ratio (φ). Since the set of rational numbers is countable, and the set of real numbers is uncountable, almost all real numbers are irrational. [1]

  8. Real number - Wikipedia

    en.wikipedia.org/wiki/Real_number

    The concept of irrationality was implicitly accepted by early Indian mathematicians such as Manava (c. 750–690 BC), who was aware that the square roots of certain numbers, such as 2 and 61, could not be exactly determined. [7] Around 500 BC, the Greek mathematicians led by Pythagoras also realized that the square root of 2 is irrational.

  9. Transcendental number - Wikipedia

    en.wikipedia.org/wiki/Transcendental_number

    Hence, the set of real numbers consists of non-overlapping sets of rational, algebraic irrational, and transcendental real numbers. [3] For example, the square root of 2 is an irrational number, but it is not a transcendental number as it is a root of the polynomial equation x 2 − 2 = 0.
