3/8 or 3 ⁄ 8 may refer to: 3rd Battalion, 8th Marines; the calendar date March 8 (United States) the calendar date August 3 (Gregorian calendar) the fraction, three eighths or 0.375 in decimal; a time signature; 3/8, a 2007 album by Kay Tse
[7] [8] Particularly, in geometry, it may be used either to show that two figures are congruent or that they are identical. [9] In number theory, it has been used beginning with Carl Friedrich Gauss (who first used it with this meaning in 1801) to mean modular congruence : a ≡ b ( mod N ) {\displaystyle a\equiv b{\pmod {N}}} if N divides a ...
where C is the circumference of a circle, d is the diameter, and r is the radius.More generally, = where L and w are, respectively, the perimeter and the width of any curve of constant width.
Since 3 / 3 equals 1, multiplication by 3 / 3 does not change the value of the fraction. Second, convert 2 / 3 into fifteenths by multiplying both the numerator and denominator by five: = . Now it can be seen that
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159.The number π appears in many formulae across mathematics and physics.
The green, orange and yellow lines indicate how surface temperatures will likely respond if leading carbon emitters begin to reduce reliance on fossil fuels. Without immediate curbs, temperatures are set to follow the red track, and increase between 3.2 and 5.4 degrees Celsius by 2100. The green line shows how we can minimize warming if ...
In some cases, one may consider as equal two mathematical objects that are only equivalent for the properties and structure being considered. The word congruence (and the associated symbol ≅ {\displaystyle \cong } ) is frequently used for this kind of equality, and is defined as the quotient set of the isomorphism classes between the objects.
