    Map Transform
AI Thread Summary
A map and a transform are often used interchangeably in mathematics, typically referring to functions, but definitions can vary by context. Some texts may specify that a map is a continuous function or a homeomorphism, while transforms and operators generally denote linear functions. It's essential to refer to the specific definitions provided in your math book to clarify any distinctions. If no explicit definitions are given, they can generally be assumed to mean the same as a function. Understanding the context and any implicit properties will help clarify their usage.

Is there a diffrence between a map and a transform or are they the same thing? My math book uses the term map but i studyed transforms in lin alg and they seem like the same thing. please help me get this straight in my head.

Depends on the book/subject. function, map, transform and operator are usually synonyms, but some books define one of the latter to be something special, if it's used a lot. E.g. a map may be defined to be a continuous function, or a homeomorphism. Transforms and operators are usually linear functions.

If the book doesn't explicitly define it, just assume it means function. Read some of the proofs to see if any special properties are implicitly assumed, eg continuity or linearity.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
