Uniqueness - Ichiika

Japanese: 一意化 - いちいか
Uniqueness - Ichiika

...By eliminating t from the two equations, we obtain the equation of the curve of the form F ( x , y )=0. Conversely, when there is an implicit function defined by the equation F ( x , y )=0, expressing x and y as single-valued functions of the parameter t in the form x =φ( t ) and y ψ( t ) is called uniformization. For example, the equation x2y2-1 =0 is uniformized by...

Japanese:

…二つの方程式からtを消去すればF(x,y)=0という形の曲線の方程式を得る。逆にF(x,y)=0なる方程式で定義される陰関数があるとき,xyとをパラメーターtの1価関数としてx=φ(t),y=ψ(t)の形に表すことを一意化という。例えば,方程式x2y2-1=0は,により一意化される。…
