y=sin2x的导数是2cos2x。拓展知识：1、导数（Derivative），也叫导函数值。又名微商，是微积分中的重要基础概念。当函数y=f（x）的自变量x在一点x0上产生一个增量Δx时，函数输出值的增量Δy与自变量增量Δx的比值在Δx趋于0时的极限a如果存在，a即为在x0处的导数，记作f’（x0）或df（x0...
方法如下，请作参考：
cos2x的导数：-2sin2x。这是一个复合函数的导数，有两层，外层是cos的导数，内层是2x的导数，所以(cos2x)'=-sin2x*(2x)的导数=-2sin2x。解：(cos2x)'。=-sin2x*(2x)'。=-2sin2x。导数，也叫导函数值。又名微商，是微积分中的重要基础概念。当函数y=f（x）的自变量x在一点x0上产生一...
