| Abstract: | In this paper we study the parabolic arch. Then, we discuss the relation between the triangle and its minimum parabolic arch. As to calculation of the area of a curve trapezoid we obtain some approximate formulas which generalize the Simpson's formula. Finally,we give several examples as their application. |
