| Abstract: | In this article, by using the derivative formulas and finding derivative rules, we give a theorem for discriminating whether a piecewise function is derivable at the point of division and how to find its derivative if it is derivatable. Examples are also given about the applications and disadvantages of this theorem. |

| Keywords: | piecewise function point of division derivative |
