in-pingere(fasten, drive in)

implicit
in-plic(fold)-it
adj.暗指的 [ implied, rather than expressly stated]
ex. Her silence gave implicit consent.
她的沈默表示默許。
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。
