Trigonometric identities mnemonic. Another mnemonic permits all of the basic identities to be read off quickly. The hexagonal chart can be constructed with a little thought: [10] Draw three triangles pointing down, touching at a single point. This resembles a fallout shelter trefoil. Write a 1 in the middle where the three triangles touch
The mnemonic "SOHCAHTOA" (occasionally spelt "SOH CAH TOA") is often used to remember the basic trigonometric functions: [37] Sine = Opposite / Hypotenuse; Cosine = Adjacent / Hypotenuse; Tangent = Opposite / Adjacent; Other mnemonics that have been used for this include: Some Old Hippie Caught Another Hippie Tripping On Acid.
Knuckle mnemonic. A mnemonic for the number of days in each month uses the knuckles (and the dips between them) of two fists, held together, moving right from the left pinky knuckle. The raised knuckles can be seen as the 31-day months, the dips between them as the 30-day-months (and February). The gap between the hands ignored.
A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters. It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ.

A mnemonic link system, sometimes also known as a chain method, is a method of remembering lists that is based on creating an association between the elements of that list. For example, when memorizing the list (dog, envelope, thirteen, yarn, window), one could create a story about a "dog stuck in an envelope, mailed to an unlucky thirteen ...

Visual mnemonic charts have been devised over the ages. Baden-Powell included one in the Girl Guides handbook [1] in 1918. A contemporary Morse code chart. Here is a more up-to-date version, ca. 1988: Other visual mnemonic systems have been created for Morse code, mapping the elements of the Morse code characters onto pictures for easy ...
