The ratio for a perfect octave is 2:1. This means that if one note has a frequency of ( f ), the note an octave higher will have a frequency of ( 2f ). This relationship creates a harmonious sound, as the higher note resonates at double the frequency of the lower note.
current ratio = current assets / current liablities A ratio (in trig) is simply the division of two lengths. A tangent (in trig) is the ratio of the opposite and adjacent legs.
Trig ratios or to give them their proper name are trigonometrical rations applicable to right angle triangles and they are tangent ratio, sine ratio and cosine ratio.
of what?
The tangent is the ratio of sine over cosine; also, in a unit circle, Y over X.

2:1
Pythagoras discovered that the ratio for creating an interval of a perfect octave is 2:1. This means that when one string vibrates at a frequency of a certain pitch, the string that is an octave higher vibrates at double that frequency. By using two strings of the same tension and varying their lengths, he found that shortening the string to half its length produces this harmonious interval. This principle laid the foundation for understanding musical harmony and the mathematical relationships between musical notes.

Pythagoras discovered that the interval of an octave can be represented by the ratio 2:1. This means that if one note has a frequency of ( f ), the note an octave higher will have a frequency of ( 2f ). This ratio is fundamental in music theory, as it creates a harmonious sound that is pleasing to the ear. Pythagoras's work laid the groundwork for understanding musical scales and the mathematical relationships between different pitches.
Perfect octave.
perfect fourth
In music, an octave refers to a musical interval between two notes that have a frequency ratio of 2:1. This means that the higher note is double the frequency of the lower note, creating a sense of similarity and harmony between the two notes.

The Pythagorean interval, often referred to in music, can be represented by the ratio of string lengths. When two strings are stretched to create musical intervals, if one string is played at a length ratio of 2:1, it produces an octave. However, if you mentioned a ratio of 21, it could refer to a specific interval or tuning system. Generally, in the context of Pythagorean tuning, different ratios correspond to various musical intervals, with the most common ones being 3:2 for a perfect fifth and 4:3 for a perfect fourth.
