构造法是高中数学的一个难点,在导数的应用中也有构造函数这种应用,一些看似新颖的试题,其实并不新颖,只要你牢记教材上的8个公式和4个运算法则,掌握一些常见的变形技巧,就很容易构造出所需要的函数.一、活用积商导数法则构造新函数(导数相关的原函数) Construction method is a difficult high school mathematics, the application of the derivative also has the constructor function of this application, some seemingly novel questions, in fact, is not new, as long as you keep in mind the 8 formulas and 4 algorithms, to master some Common deformation techniques, it is easy to construct the required functions. First, the use of derivative rules to construct a new derivative function (the derivative of the original function)
