Some day, there will be another square root of 3, quietly come waltzing by.
有一天，将会有另一个根号3，轻轻地踏着华尔兹而来。
Similarly 120 degrees will form a side the length of which is the square root of 3 times the arm length.
简而言之，夹角是120度的三角形形成第三边长度是3的平方根乘以手臂的长度。
And the same with the third one. Well, you will get, 3 after simplifying, u3 over square root of u3 u3/ Now, that means this guy equals this guy equals this guy.
第三个也是一样，所以最后简化之后你会得到3,√=λ，squared，plus，h，squared，equals，lambda。,也就是说，这个等于这个，还有这个。
For example, in Listing 3, it would be good to receive an error message when doing square-root (-22.0) and exiting the program with return status -1 instead of returning -1.0.
例如，在清单3中，当执行square - root(- 22.0)时应该产生错误消息，程序退出，返回状态应该是- 1而不是- 1.0。
