求sin^2(2x+π/3)的导数这样写为什么不对:[sin^2(2x+π/3)]'=[sin(2x+π/3)·sin(2x+π/3)]'=2[sin(2x+π/3)]'·sin(2x+π/3)=2cos(2x+π/3)·sin(2x+π/3)=sin(4x+2π/3)

求sin^2(2x+π/3)的导数这样写为什么不对:[sin^2(2x+π/3)]''=[sin(2x+π/3)·sin(2x+π/3)]''=2[sin(2x+π/3)]''·sin(2x+π/3)=2c
求sin^2(2x+π/3)的导数这样写为什么不对:[sin^2(2x+π/3)]'=[sin(2x+π/3)·sin(2x+π/3)]'=2[sin(2x+π/3)]'·sin(2x+π/3)=2cos(2x+π/3)·sin(2x+π/3)=sin(4x+2π/3)
求sin^2(2x+π/3)的导数
这样写为什么不对:
[sin^2(2x+π/3)]'
=[sin(2x+π/3)·sin(2x+π/3)]'
=2[sin(2x+π/3)]'·sin(2x+π/3)
=2cos(2x+π/3)·sin(2x+π/3)
=sin(4x+2π/3)
求sin^2(2x+π/3)的导数这样写为什么不对:[sin^2(2x+π/3)]'=[sin(2x+π/3)·sin(2x+π/3)]'=2[sin(2x+π/3)]'·sin(2x+π/3)=2cos(2x+π/3)·sin(2x+π/3)=sin(4x+2π/3)
你的内函数,就是2x+pi/3 没有求导,我拍照给你看
=[sin(2x+π/3)·sin(2x+π/3)]'
=2[sin(2x+π/3)]'·sin(2x+π/3)
=2cos(2x+π/3)·sin(2x+π/3) ×(2x+3)' 复合函数还要继续求导
=2sin(4x+2π/3)
求sin^2(2x+π/3)的导数这样写为什么不对:[sin^2(2x+π/3)]'=[sin(2x+π/3)·sin(2x+π/3)]'=2[sin(2x+π/3)]'·sin(2x+π/3)=2cos(2x+π/3)·sin(2x+π/3)=sin(4x+2π/3)
