One half is the multiplicative inverse of 2. It is an irreducible fraction with a numerator of 1 and a denominator of 2. It often appears in mathematical equations, recipes and measurements.
One half is the multiplicative inverse of 2. It is an irreducible fraction with a numerator of 1 and a denominator of 2. It often appears in mathematical equations, recipes and measurements. The area of a triangle is one half its base and its height, also known as its altitude. of the modular j-invariant in the upper half-plane (shaded gray ), with modular discriminant |\tau| \ge 1 and -\tfrac{1}{2} , where -\tfrac{1}{2} 1 The gamma function evaluated at one half is the square root of pi. It has two different decimal representations in base ten, the familiar 0.5 and the recurring 0.4\overline{9} , with a similar pair of expansions in any even base; while in odd bases, one half has no terminating representation. The Bernoulli number B_{1} has the value \pm \tfrac {1}{2} (its sign depending on competing conventions). The Riemann hypothesis is the conjecture that every nontrivial complex root of the Riemann zeta function has a real part equal to \tfrac {1}{2} .
