ps.

implicit differentiation = 隱微分 ...(純粹補充，看不懂沒關係)

例如：f(x,y)=x²+y²=C

(d/dx)f(x,y)

=> (d/dx)[x²+y²]=0

=> dx²/dx+(dy²/dy)(dy/dx)=0 

=> 2x+2y(dy/dx)=0

=> dy/dx=-x/y

explicit differentiation則是將函數寫成顯函數，再來作微分運算。

例如：x²+y²=C => y=±√(C-x²)

dy/dx=±(1/2)(C-x²)^-1/2(-2x)  

=±(-x)/√(C-x²)

如果將±√(C-x²)以y取代-->  dy/dx=-x/y

與implicit differentiation結果相同。
