求一个数学和英文都不错的能人,求解以下这几题.看不懂的就打酱油吧.
Determine whether or not F is a conservative vector field.If it is,find a function f such that F = f.If it is not,enter NONE.
F(x,y)=(exp(x) sin(y) i+ (exp(x) cos(y)) j

哈哈,你这个问题不仅仅是数学和英语还有物理知识.
碰巧我是学电子的,这是电磁波里面的一个问题.用保守矢量场的性质来即可.
如果一个向量场是某个标量势的梯度,那么便称为保守向量场.
因为不会打偏导数的符号就口述一下.
构造函数f对f分别求关于x和y偏导数,使他满足他的梯度等于F△F.即可.
