x max-
It 's going to oscillate between plus x max and minus x max.
它会在+x最大值，和-x最大值之间震荡。

The total energy that I started with if I release it here at zero speed equals ^ 2 one-half k x max squared .
开始的总能量，如果我在这里释放它，初速为0，总能量，=1/2kx的最大值。

And I continued the problem correctly , because I wrote down here one-half k x max squared , which is exactly this term .
继续正确解答这个问题，因为我在这里写下，1/2xmax^2，就是这一项。
