Despite the greatest strides in mathematics, these hard math problems remain unsolved. Take a crack at them yourself.
John worked hard he managed to find out a solution to t he math problem.相关知识点: 试题来源: 解析 so;that 结合上文的句意约翰工作非常努力,他设法找出解决这个数学问题的方法,也就是说约翰工作是如此努力以致于他设法去找出解决这个数学问题的方法。故用so/such…that表示如此以至于连接成一个句子,that...
John worked ___ hard ___ he managed to find out a solution to the math problem. 相关知识点: 试题来源: 解析 sothat 给定句句意:约翰工作很努力。他设法找到解决数学问题的方法。这是两个简单句,我们可将他们合并为一个复合句:约翰工作如此努力以致他设法找到了解决数学问题的方法。所以在改写后句子的...
该算法是为了求解M-稀疏问题(M-sparse problem)式(3.1)而提出的,经过一番推导得到了迭代公式式(3.2),其中HM(·)的含义参见式(3.3)。 这里面最关键的问题是:式(3.2)这个迭代公式是如何推导得到的呢? 2、Step1:替代目标函数 首先,将式(3.1)的目标函数用替代目标函数(surrogate objective fucntion)式(3.5)替换...
While weighing one large marble with 8 small marbles, the student discovers that the large marble’s weight is 5 times the average (arithmetic mean) of the weight of the small marbles. The large marble’s weight is what fraction of the total weight of the 9 marbles? 3 17. The function...
I used to solve ABC before I quit and when I came back I barely solved B despite it not being a knowledge problem or math problem. It's just that the problems now are more logic-based which is a skill that needs sharpening and practice. Continuous practice to be exact, as leaving or...
