微分方程(siny+y^2sinx)dx+(xcosy-2ycosx)dy=0.求详解.
绝对值的导数f(x,y)=|y|cos(x)求fx(0,0)fy(0,0)
(cosy+ycosx)dx+(sinx-siny)dy=0
已知函数fx 满足fx+fy=f(x+y)+2 当x>0时,fx>2 求fx在R上是增函数
求函数z=sinx+siny+sin(x+y)(0
fx是定义在(0,正无穷)上的增函数,且f(x/y)=fx-fy求f1 若f6=1,解不等式f(x+3)-f(1/x)<
已知fx的定义域为0到负无穷,且函数f2=1,fxy=fx+fy,当x>y时.fx>fy,(1)求f1,f4的值.(2)
设二维随机变量(x,y)概率密度函数为f(x,y)={6x,0<x<1,0,其他},求X,Y边缘概率密度fx(x),fy
求sin(x+y)=sinx+siny的导数
已知函数fx满足fx=-f(-x),并对任意x,y属于R,总有fx+fy=f(x+y),切当x>0时,fx
已知函数fx对任意x,y∈R,总有fx+fy=fx+y,且当x>0时,fx<0,f(-1)=2 求证:fx在R上是减函数
已知函数fx的定义域是0到正无穷 且满足fxy=fx加fy f1/2=1如果对于x大于0小于y 都有fx大于fy 求f1
