三角形

Then interpolating cubature formulae is given based on Lagrange interpolation formulae. Secondly it make use of the cubature formula on the triangle to construct cubature formulae on the correspondent spherical triangle.

通过把其定义域上的积分化为平面单纯形{u =(u1， u2， u3)： u1 + u2 + u3 = 1， u1， u2， u3〉0}上的积分，然后利用平面单纯形上数值积分公式给出其在球面三角形上的对d次齐次多项式精确成立的Gauss求积公式的构造方法。

Through this translation, European mathematicians got to know methods for calculating the areas of triangles, volumes of spheres as well as square and cube root .

通过这种翻译，欧洲数学家开始接触三角形的计算模型，同样也有关于球体，矩形和立方根的卷册。

Turn off culling, so we see the front and back of the triangle
