The ratio for creating the interval of a perfect octave is 2:1. This means that if you take a fundamental frequency, doubling it produces the note that is one octave higher. For example, if the fundamental frequency is 440 Hz (the note A4), the octave above it (A5) would be 880 Hz. This doubling of frequency creates a harmonious sound that is perceived as the same note at a higher pitch.
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.

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.

Pythagoras discovered that the ratio for creating a perfect octave is 2:1, meaning that when the length of one string is half that of another, the higher pitch produced corresponds to an octave above the lower pitch. This finding highlighted the mathematical relationship between string length and frequency, illustrating how tension and vibration contribute to musical harmony. Thus, when two strings are stretched to the same tension, their lengths determine the musical intervals they create.
