Y=cosX^2 求dy
Y=cosX^2 求dy
Y=cosX^2 求dy
dy=dcos(x²)
=-sin(x²)dx²
=-sin(x²)*2xdx
=-2xsin(x²)dx
dy=dcos(x^2)
dy=2x[-sin(x^2)]dx
dy=-2xsin(x^2)dx
Y=cosX^2 求dy
y=2^(-1/cosx)求dy
y=f((sinx)^2)+f((cosx)^2) 求dy/dcosx ,dy/d(cosx)^2)
求dy/dx=x/y+(cosx/y)^2通解
y=cosx+In^2X.求dy=?
函数y=x^2/cosx求dy
y=cosx+ln^2x求dy在线等
已知y=x^cosx/2,求dy/dx,
y=2^x-cosx/1-x 求dy
y = ln(cosx),求微分dy
y=cosx/x 求微分dy
y=(1+cosx)/(sinx) 求dy?
y=x^3/cosx 求dy
y=(1+cosx)^5 求dy
已知y=xsinx+cosx,求dy
设y=1+cosx / 1-cosx,求dy / dx
y=1+cosx/1-cosx 求dy
dy/dx-y=cosx
