So, let me point out -- this is a change in concavity, maybe right about in this x region we want to change concavity and then this x region we want to change concavity. 帮我翻译下术语阿,我翻得很烂唉
那么让我指出--这个凹的改变也许恰好在这个我们想改变凹的x区域,在这个x区间我们想改变凹性
所以,让我指出—扰大—这是一个肆衫改变,也许对在凹在这个x
地区裂李腔,我们想要改变凹,然后这些x地区,我们想要改变凹。
因此,让我们指出吧--这个凹的改变,也许是我们想改变的这个地区,我们想要把这个地区变凹。
So let me point out that The sunken change maybe at the very we want to change the sunken x area, we want to change the concave in this x interval.
