Remember, I said when we do a bisection method, we're assuming the answer lies somewhere between Well, what is the square root of a quarter?

记住，我提过当我们用二分法的时候,我们假设答案处于,上边界和下边界之间,0。 25的平方根是多少？

All right. I tried it on 2, I surely didn't expect a precise and exact answer to that but I got something, and if you square this, you'll find the answer kept pretty darn close to 2.

好，我试试求2的平方根，我当然不希望得到一个完全准确的答案了，但是我得到了一个近似值，试试将这个数平方一下，你会发现结果和2相当接近。
