y=x^3+ln3+3^x,求:dy/dx

y=x^3+ln3+3^x,求:dy/dx 紧急.x+y-3^xy=0.求微分.不是微分方程.dy-3^（xy）•ln3（dx•y dy•x）=0. y=e^x-ln3 则 dy/dx等于什么, y=sin(x^2),求dy/d(x^3) y=sin(x^3),求dy/d(x^2) y=-ln3,求dy= 已知y=2x-√x+3sinx-ln3,求导数y'x? y=3x+sin2x求dy, y=x^3/cosx 求dy y=tan2xln(3x) 求dy y=f(-x^3)求dy y=2x∧3 lnx x>o 求dy/d x 设参数方程x=2t^3+2,y=e^2t 确定函数x=x(y),求dx/dy,d^2x/dy^2 y=x^2+3x+1 求dy y=e^-x cos 3x,求dy. 微积分y=3^x＋cose^x,求dy 设y=3^x+core^x,求dy y=4^x+x^3 求dy
