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.

Every pitch has frequency. Frequency is actually an exponential function, meaning that for every octave the pitch increases, the frequency of the sound wave doubles, so A4 = 440 htz, A5 = 880 htz, A6 = 1760 htz, etc. The human ear finds consonance when the ratio of the two notes in the interval is simple, such as 1:2, 3:4, or 2:3. When the ratio is not simple, such as __, the interval is dissonant. Two notes in unison, the most consonant, have ratio 1:1 (same pitch). Then the order goes: octave (2:1), perfect fifth(3:2), perfect fourth (4:3), and so on, each interval more dissonant than the last, ending on the augmented fourth (45:32)
The term 'octave' is the name for an interval(space) between two notes. The frequency of the note is doubled, or halved, depending on whether the interval goes up or down in frequency. The two notes are heard toghether as the same, and will also have the same name. For example, an octave above A(440 Hz) is A(880 Hz) an octave under A(440 Hz) is A(220 Hz) To answer the question, the similarity between the keynote and an octave above it, is that the ratio between the frequency of these notes is 1:2 and of course, their names.
The musical interval between two notes depends on the ratio of their frequencies. An octave is a ratio of 2:1 and, in equal temperament comprises 12 equal semitones, which therefore have a ratio of 21/12.
It is ratio.
