WebApr 5, 2024 · 结果为：f(x,y)=x²(y+1)/(y-1) 解题过程如下： f(x-y,y/x)=x^2-y^2. 令a=x-y. b=x/y. 则x=by. a=by-y. y=a/(b-1) x=ab/(b-1) 则x+y=a(b+1)/(b-1) 所以x²-y²=a²(b+1)/(b-1) f(a,b)=a²(b+1)/(b-1) ∴f(x,y)=x²(y+1)/(y-1) 扩展资料. 两个复系数的多项式之比为有理函数，它实现扩充的复平面到自身的解析映射。 WebLet $f:X\to Y$ where $X$ and $Y$ are nonempty.

WebApr 30, 2024 · 19. You can prove that f ( x) ≡ x in four fairly simple steps: Show that f is one-to-one. Assume f ( x) = f ( y) and show that this implies x = y by applying f two times to each side of the equation. Show that a continuous function that is one-to-one has to be strictly increasing or decreasing. This follows for example by the mean-value theorem. stories about zoo animals https://bodybeautyspa.org
