关于流体力学的题
The components of a velocity field are given u=x+y v=xy^3+16 and w=0.Deternine the location of any stagnation points (V=0)in the flow field.其实就是求出以后画出他们的函数图.可能是关于欧拉方程和拉朗格日方程吧 dx/dy=v/u 我也不太清楚

要找出所有停滞点的位置坐标.
w=0,只要同时满足u=0 v=0.
联解 x+y=0
xy^3+16=0
得停滞点坐标为：x=-2,y=2 和 x=2,y=-2
这是欧拉描述法.

An electric field in a given region of space is given by E=2 The accompanying figure shows the velocity v(t) of a particl What do you think are the most important components of a pra 多元函数偏导难题u=f(ux,v+y);v=g(u-x,v^2y)...f,g 可微,求u关于x的偏导及v关于x的偏导一道复变函数题,由下列已知调和函数求解析函数f(z)=u(x,y)+iv(x,y).并写成关于z的表达式v(x,y)=a 已知向量u=(x,y)与向量v=(y,2y-x)的对应关系用v=f(u)表示求证：对于任意向量a find the differential dy of the given function y=3x^(2/3) 英语翻译therefore,the basic components of positive self-esteem a 设A= x 0,B= u v,C= 3 -4,若A+2B-C=0,求x,y,u,v的值 field trips are a lot of fun 设y=u^v,u,v是x的可导函数,证明：dy/dx=u^v(v/u*du/dx+lnu*dv/dx) U、v、x、y开头的英语单词
