[y+(x^2)y]dy=[x(y^2)-x]dx ,dy=x(e^x)(1+y^2)dx 这两题的通解

y=x^2x,求dy dy/dx=2y/x+3x/2y x^y-y^x=2,求dy/dx 求dy/dx=(x-y+5)/(x+y-2) （-2x-y+9)dy=(-y+x+3)dx y=e^2x,dy= 微分方程 dy/dx=(-2x)/y y=sinx/x^2,求dy y=x×2^arcsinx 求dy y=e^-x^2,求dy y=e^2x则dy? y=(tanx)/x^2,求dy y=xsin 2x,求dy y=(cos^2x) 求dy dy/dx=(2x*x*x*y-y*y*y*y)/(x*x*x*x-2x*y*y*y) (x^2)dy+（y^2)dx=dx-dy x^2+y^2=e^y求dy/dx 求dy/dx=x/y+(cosx/y)^2通解
