x^2y^2-2x=3, 求d'y/dx这道题真难,想了好久都不知道怎么做,解答时请按步骤来做:1.先解导dy/dx2.再解导d'y/dx这样我会明白些,这题目是初级的,请不要用sine,cosine,tagent来解答.书本的答案是(xy^3-2y)/(x^2y

d/dx((x^2+y^2)^2)=d/dx(x^2-y^2),求（化简）dy/dx=? x^y-y^x=2,求dy/dx 求dy/dx=(x-y+5)/(x+y-2) z=x^2-y/x+y,而y=2x-3,求dz/dx. y=(1+x^2)arctan x 用MATLAB求(d^2*y)/dx^2 设y=ln(x+根号(x^2+4),求d^2y/dx^2 求方程 dy/dx+x(y-x) +x^3(y-x)^2=1的通解~ 求微分 方程y-2x=(x-y)ln(x-y) 求dy/ dx 和d^2y/ dx^2如题··设函数y=y(x) 由方程y-2x=(x-y)ln(x-y)所确定 求dy/ dx 和d^2y/ dx^2有公式什么的···谢谢··· 求微分方程初值y^3d^2y/dx^2+1=0,y|x=1=1,dy/dx|x=1=0 x^2+xy+y^3 求d^2y/dx^2用 dy/dx=-F'x/F'y 计算此二阶导数,怎么计算 已知dx/dy=1/y′,求d（2）y/d x^2? 已知DX=25,DY=36,ρ=0.4,求D(X+Y),D(X-Y),D(2X+3Y) e^y+xy=e 求 d^2y/dx^2｜x=0 求详解 x^2+y^2=e^y求dy/dx dy/dx=2y/x+3x/2y 求dy/dx=x/y+(cosx/y)^2通解 已知x=y^2-4y,求dy/dx （-2x-y+9)dy=(-y+x+3)dx
