To remember the order of taxa in biology (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species, [Variety]): " D ear K ing P hilip C ame O ver F or G ood S oup" is often cited as a non-vulgar method for teaching students to memorize the taxonomic classification of system.
The quadratic formula is exactly correct when performed using the idealized arithmetic of real numbers, but when approximate arithmetic is used instead, for example pen-and-paper arithmetic carried out to a fixed number of decimal places or the floating-point binary arithmetic available on computers, the limitations of the number representation ...
The indifference of this rootless harmony to tonality places the burden of key verification upon the voice with the most active melodic line. [2] Quintal harmony (the harmonic layering of fifths specifically) is a lesser-used term, and since the fifth is the inversion or complement of the fourth, it is usually considered indistinct from quartal ...
Figure 1. Plots of quadratic function y = ax 2 + bx + c, varying each coefficient separately while the other coefficients are fixed (at values a = 1, b = 0, c = 0). A quadratic equation whose coefficients are real numbers can have either zero, one, or two distinct real-valued solutions, also called roots.
The red cat and an ox mnemonics are useful to remember the same. Red cat: Reduction at cathode; An ox: Anode for oxidation. [32] PANIC : Positive Anode, Negative Is Cathode; The words oxidation and anode, both begin with vowels. Also, both reduction and cathode begin with consonants. [29] Fat Cat: electrons flow From Anode To Cathode
Signs of trigonometric functions in each quadrant. All Students Take Calculus is a mnemonic for the sign of each trigonometric functions in each quadrant of the plane. The letters ASTC signify which of the trigonometric functions are positive, starting in the top right 1st quadrant and moving counterclockwise through quadrants 2 to 4.
Minor chords are noted with a dash after the number or a lowercase m; in the key of D, 1 is D major, and 4- or 4m would be G minor. Often in the NNS, songs in minor keys will be written in the 6- of the relative major key. So if the song was in G minor, the key would be listed as B ♭ major, and G minor chords would appear as 6-.
As its alternative name AABA implies, this song form consists of four sections: an eight-bar A section; a second eight-bar A section (which may have slight changes from the first A section); an eight-bar B section, often with contrasting harmony or "feel"; and a final eight-bar A section. The core melody line is generally retained in each A ...
