Find two vectors that are not * * * lines in the plane, and multiply the two vectors by zero to determine the required normal vector. In order to facilitate the operation, the common factor is extracted. If it contains the unknown quantity X, which is the value of generation X, the simplest normal vector can be obtained.

If the known vectors A and B are two non-zero vectors, which are not * * * lines in the plane ι, and a=(x 1, y 1, z 1), b=(x2, y2, z2), let n be the normal vector of the plane ι, and n =

Matters needing attention in math answering:

1, skillfully solve multiple-choice questions, fill in the blanks, solve multiple-choice questions, fill in the blanks. The basic principle is not to make a mountain out of a molehill.

2. directly consider the stem of the question, explore the results, consider the stem of the question and the choice together, and explore the conditions to meet the stem of the question from the choice.

3. Normative answers are very important. After finding a solution, writing should be concise, fast and standardized, and the scores of college entrance examination should be graded step by step. Key steps should not be lost, and non-key steps should be omitted reasonably.

4. Try to use mathematical symbols when answering questions, which is more time-saving and rigorous than text narration. Even if the process is relatively simple, the basic steps should be briefly written out, otherwise points will be deducted.
