最近开始做GWD,发现数学里有好几次看到一个莫名的字母 V , 如:If x >0.9,which of the following could be the value of X? A. v0.81 B.v0.9 C.(0.9)*(0.9) D.(0.9)*(0.99) E.1-v0.01 答案是B 我就很莫名,这个V是什么东东?
PS:如果说1被3divide,那余数算几呢?
PPS: 如果说A is proportional to its thickness and also proportional to the square of its length....
那转换成数学语言,是A=k1*THICKNESS +K2*(LENGTH*LENGTH) 还是分开来,A=K1*thickness and A=K2*(LENGTH*LENGTH)
