二. 学会求函数的值域或复合函数(composite function)的值域 对于one to one函数,直接带入定义域的两端点值即可得最大值和最小值 对于many to one函数,需要确定是否有极大值点和极小值点,并通过带入两端点值及极大值或极小值来确定值域 三. 反函数(inverse function) 反函数的本质是横坐标和纵坐标互换,即x...
Functions A function expresses the relationship between variables. Values of these variables can be numbers or nonnumerical objects such as geometric figures,
inverse function- a function obtained by expressing the dependent variable of one function as the independent variable of another; f and g are inverse functions if f(x)=y and g(y)=x function,mapping,mathematical function,single-valued function,map- (mathematics) a mathematical relation such that...
设置InverseFunctions->False,Solve 不使用反函数:In[1]:=Out[1]= 这里,使用基于 Reduce 的方法,因为它不要求使用反函数:In[2]:=Out[2]=代数方程求解不需要用反函数:In[3]:=Out[3]= 参见 FindRoot 技术笔记 一元方程 历史 1991年引入 (2.0)
"Let f and g be two functions such that f(g(x))=x and g(f(x))=x.The function g is called an inverse function of the function, f and vice versa".Since f(g(x))=x and g(f(x))=x, the functions f(x)= 1(x+1) and g(x)= (1-x)x are inverse functions of each othe...
