In Euclidean geometry, the two acute angles in a right triangle are complementary because the sum of internal angles of a triangle is 180 degrees, and the right angle accounts for 90 degrees. The adjective complementary is from the Latin complementum , associated with the verb complere , "to fill up".
These identities are useful whenever expressions involving trigonometric functions need to be simplified. An important application is the integration of non-trigonometric functions: a common technique involves first using the substitution rule with a trigonometric function, and then simplifying the resulting integral with a trigonometric identity.
In computer-aided design the preferred term for a parallel curve is offset curve. [ 2 ] [ 3 ] [ 4 ] (In other geometric contexts, the term offset can also refer to translation . [ 5 ] ) Offset curves are important, for example, in numerically controlled machining , where they describe, for example, the shape of the cut made by a round cutting ...
The Lewis offset is a term for the portion of the central groove on a permanent mandibular first molar which lies between the two central pits. It was named for long time dental anatomy instructor Dr. Christopher S. Lewis, a Mercer Island, WA dentist.
Offset (computer science), the distance to (displacement of) an element within a data object; Offset (gears), the perpendicular distance between the axes of hypoid or offset-facing gears; Offset (geometry), see parallel curve; Offset (geophysics), the distance between a source and receiver of seismic or other geophysical readings
WASHINGTON (Reuters) -President-elect Donald Trump has urged the U.S. Supreme Court to pause implementation of a law that would ban popular social media app TikTok or force its sale, arguing he ...
The fact that the complement of a perfect graph is also perfect is the perfect graph theorem of László Lovász. [4] Cographs are defined as the graphs that can be built up from single vertices by disjoint union and complementation operations. They form a self-complementary family of graphs: the complement of any cograph is another different ...
