Although intonation is primarily a matter of pitch variation, it is important to be aware that functions attributed to intonation such as the expression of attitudes and emotions, or highlighting aspects of grammatical structure, almost always involve concomitant variation in other prosodic features.andarin Chinese is a tonal language, meaning that pitch contours within a word distinguish the word from other words with the same vowels and consonants. Nevertheless, Mandarin also has intonation patternsâpatterns of pitch throughout the phrase or sentenceâthat indicate the nature of the sentence as a whole.
A reflection is a map that transforms an object into its mirror image with respect to a mirror, which is a hyperplane of fixed points in the geometry. For example, a reflection of the small Latin letter p with respect to a vertical line would look like a q.
Translation: In a translation, everything is moved by the same amount and in the same direction. Every translation has a direction and a distance. Rotation: A rotation fixes one point (the rotocenter) and everything rotates by the same amount around that point. Every rotation has a rotocenter and an angle. Reflection: A reflection fixes a mirror line in the plane and exchanges points from one side of the line with points on the other side of the mirror at the same distance from the mirror. Every reflection has a mirror line. Glide Reflection: A glide reflection is a mirror reflection followed by a translation parallel to the mirror.
