举一反三
- Eat to your ______,and drink to your_______.? right, left|right, right;|left, left|left, right
- 若\({y_1}\left( x \right), {y_2}\left( x \right)\)都是\(y' + P\left( x \right)y = Q\left( x \right)\)的特解，且 \({y_1}\left( x \right), {y_2}\left( x \right)\) 线性无关，则通解可表为\(y\left( x \right) = {y_1}\left( x \right) + C\left[ { { y_1}\left( x \right) - {y_2}\left( x \right)} \right]\)。
- 设\( A,B \)均为\( n \)阶方阵，则必有（ ） A: \( \left| {A + B} \right| = \left| A \right| + \left| B \right| \) B: \( AB = BA \) C: \( \left| {AB} \right| = \left| {BA} \right| \) D: \( {\left( {A + B} \right)^{ - 1}} = {A^{ - 1}} + {B^{ - 1}} \)
- 设\( A,B \) 为方阵，则 \( \left| {AB} \right| = \,\left| A \right|\,\left| B \right| \)。（ ）
- 在网页中插入两个id名分别为left和right的标签，（）两个元素都左浮动。 A: left, B: right{float:left;} C: left, D: right{float:right;} E: left{float:left;} F: right{float:right;} G: left{width:100px;float:left;} H: right{margin-left:100px;}
