cos2x的导数是-2sin2x。一、导数的概念 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）...
We have thatI=∫0πcos2xdx=2∫0π/2cos2xdx=2∫0π/2cos2(π/2−x)dx=2∫0π/2sin2xdxand thusI=∫0π/2(cos2x+sin2x)dx=π/2 How do you use part one of the fundamental theorem of calculus to find the derivative of the functiong(x)=∫cos(t10)dt... ...
