Then, yes, we can apply Green's theorem and it will tell us that it's equal to the double integral in here of curl F dA, 0 which will be zero because this is zero.───那就可以使用格林公式了,并且我们知道,它就等于的二重积分,结果为0,因为旋度F等于。
Modem western science emerging from Italy after the Renaissance in 16th century and its founders were N Copernicus, da Vinci, F Bacon, Galileo and so on.───西方近代科学诞生于文艺复兴后的16世纪,发源地是意大利,奠基者是哥白尼、达·芬奇、培根、伽利略等人。
call that the double integral of our region, R, of f of xy dA and I will have to explain what the notation means.───称之为区域R上fdA的二重积分,会向大家解释这些符号的含义的。
So, I will -- -- compute the double integral over the region inside of curl F dA.───我会计算,在这个区域内旋度FdA的二重积分。
