- 上一篇:设a、b为非零向量,且满足(a+3b)丄(7a-5b), (a-4b)丄(7a-2b),则a与b的夹角θ=( )。
- 下一篇:设向量x垂直于向量a=2,3,-1和b=l,-2,3,且与c=2, -1,1的数量积为-6,则向量x=( )。A.(-3,3,3)
B.(-3,1,1)...
错误啦!
错误信息
- 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
