When none of the above integration rules can be applied, and if some part of the integrand is the derivative of the other part of theintegral, then we use thesubstitution method. In this method: Assume a part of the integrand to be u. ...
6、向右为x轴正方向,向下为y轴正方向,从x向y顺时针旋转所得角度以及和原点的距离,这时极坐标和直角坐标公式还是否成立,如果不成立,该是如何? 2023-10-31 00:2999回复 entropyloss1.有理数的话显然。无理数的话假定你知道这个数如何用无限位的十进制数下来表示,用经典的(a_k-m)*1/9*对应的10^-k次幂...
