设y =e^-sinx^2,则dy比dx等于多少

设y =e^-sinx^2,则dy比dx等于多少 设y-x-1/2sinx,则dx/dy= 设y=e^sinx,则dy= 设y=x^2*e^sinx,求dy. 设y=e^1-2x sinx,求dy 设x=3e^-t,y=2e^t,则dy/dx等于多少? 设x=3e^-t,y=2e^t,则dy/dx等于多少? 由方程y^2*sinx+e^y+2x=1,求dx/dy是dy/dx 打错了 若y=sinx^2,则dy/dx^2= ; dy/dx= 设φ（x^2,e^y,z）=0,而y=sinx,求dy/dx抄错了，是dz/dx dy/dx+y=e^-sinx的通解. 设y=(2+lnx)/x,则dy/dx(x=e)= 设y=e的sinx次方,则dy= 设y=e的arctanx次方,则dy= 设函数y=x^2sin(sinx),求dy/dx dy/dx-ycosx=e^sinx 设x=e^-t y=e^-2t 求dy/dx 解伯努利方程,dy/dx+y=y^2(cosx-sinx) 设函数y=sinx/e^x求dy
