If y= x^2-2x and u=2x+1, then (dy/du) =

given:
 y= x^2-2x
 u=2x+1
   y = x^2 -2
   dy/dx = 2x
    u = 2x + 1
  du/dx = 2
   dx/du = 1/2
    dy/du = dy/dx * dx/du
  dy/du = 3x * 1/2
  dy/du = 3x/2
    dy/du = 3x/2

Idon’t understand your question, can you clear it up?

The skin in the outer ear canal has special glands that produce earwax. the fance name for this waxy stuff is cerumen.after the wax is produces, it slowly makes its way through the outer ear canal to the opening of the ear.
