| Abstract: | Assume that the curve is determined by the parametric function. The limit of the type of 0/0 can be viewed as the tangent of the curve at the fixed point. The limit of the type of/can be viewed as the tangent of the curve at the infinity point. Reveals the geometric meaning of the rule from the viewpoint of parametric function. |
