Quick Answer: What Does Unique Mean In Math?

How do you prove a function is unique?

Note: To prove uniqueness, we can do one of the following: (i) Assume ∃x, y ∈ S such that P(x) ∧ P(y) is true and show x = y. (ii) Argue by assuming that ∃x, y ∈ S are distinct such that P(x) ∧ P(y), then derive a contradiction. To prove uniqueness and existence, we also need to show that ∃x ∈ S such that P(x) is true.

By the term unique solution, one mean to say that only one specific solution set exists for a given equation. So, if we have two equations, then unique solution will mean that there is one and only point at which the two equations intersect.

What is the importance of uniqueness theorem?

Theorems that tell us what types of boundary conditions give unique solutions to such equations are called uniqueness theorems. This is important because it tells us what is sufficient for inputting into SIMION in order for it to even be able to solve an electric field.

What makes a function unique?

A unique solution means it is the only solution. In your example: if (x0,y0) solves your equation then it is called unique iff the following statement is true: if (x1,y1) solves the equation, then this implies x0=x1,y0=y1.
