y=xsinx,求dx分之dyy=xsinx,求dx分之dyy=xsinx,求dx分之dyy=xsinxy''=xcosx+sinx=dy/dxy=xsinxdy/dx=xcosx+sinx
y=xsinx ,求dx分之dy
y=xsinx ,求dx分之dy
y=xsinx ,求dx分之dy
y=xsinx
y'=xcosx+sinx=dy/dx
y = xsinx
dy/dx = xcosx + sinx
y=xsinx ,求dx分之dy
y=xsinx ,求dx分之dy
Y=XsinX 求dy
已知y=xsinx+cosx,求dy
(cosx-xsinx)/(sinx+xcosx)求导这个是dy/dx 参数方程是 x=tsint+2 求 dy/dx,d^2y/dx^2y=2+tcost
y=Insin(3x-1),求dx分之dy
y=xlnx+sinx-cosx求dx分之dy
求下列函数的导数(或微分):(1)y=ln(3x^2+e^2),求dy/dx; (2)y=∫0^x cost^2 dt,求dy/dx;(3)y=xsinx,求y'';(4)y=(2xsinx+3)/x,求dy;(5)3-x^2=2y^3-y,求dy/dx;(6)y=(sinx)^lnx,求dy/dx.拜托各位大神相助了,本
若y=xsinx/根号x,求dy.
求y=X^3+Xsinx-lnX的导数dy
y=xe^y 求dy/dx
求微分方程dy/dx-ycotx=2xsinx通解如题,需要正确答案
y=(e^根号x)sinx求dy,我求出的结果是:lny=根号xsinx,y'/y=1/2根号xsinx+根号xcosx,y'=e^x(sinx/2根号x+根号xcosx),dy=e^根号x(sinx/2根号x+根号xcosx)dx那错了,答案是;dy=e^根号x(sinx/2根号x+cosx)dx
设函数:y=xsinx^2,求dy/dx.我算的是=sinx^2+x2sinxcosx,但是答案是:sinx^2+2x^2cosx^2
(dy/dx)-y=x求微分方程
y=(sinx)^x 求DY/DX
y=ln sinx,求Dy/Dx
y=x+lnx,求dx/dy
