## What is the effect of a synecdoche?

Synecdoches allow speakers to emphasize certain parts of a whole, highlighting their importance by substituting them for the whole. They also draw attention to the power of associative and referential thinking, as readers automatically understand that a part can stand for the whole and vice versa.

## Why are they called hyperbolic functions?

Just as the ordinary sine and cosine functions trace (or parameterize) a circle, so the sinh and cosh parameterize a hyperbolaâ€”hence the hyperbolic appellation. Hyperbolic functions also satisfy identities analogous to those of the ordinary trigonometric functions and have important physical applications.

## What does hyperbolic mean in math?

In mathematics, hyperbolic functions are analogues of the ordinary trigonometric functions, but defined using the hyperbola rather than the circle. Just as the points (cos t, sin t) form a circle with a unit radius, the points (cosh t, sinh t) form the right half of the unit hyperbola.

## How does metonymy work?

Metonymy is the use of a linked term to stand in for an object or concept. Sometimes metonymy is chosen because it’s a well-known characteristic of the concept. A famous example is, “The pen is mightier than the sword,” from Edward Bulwer Lytton’s play Richelieu.

## Why do authors use metonymy?

Why Writers Use it: Metonymy can often allow writers and speakers to refer to complicated concepts or large groups of people with a single world. It also helps to create a quick mental image by using everything that the metonym evokes.

## Is Sinh the same as sin 1?

No, sinh is a hyperbolic function of sine. Sin^-1 is inverse of sine. You use the inverse to find angles. To enter sinh to press hyp then sin.

## What is repetition as a figure of speech?

Repetition is a literary device in which a word or phrase is repeated two or more times. Figures of speech that employ repetition usually repeat single words or short phrases, but some can involve the repetition of sounds while others might involve the repetition of entire sentences.
