Abstract:Aiming at the issues of implicit function derivation,based on the existence theorem of implicit function,five methods of implicit function derivation are summarized;Meanwhile,this five methods are used to solve univariate implicit function and bivariate implicit function respectively,moreover,the advantages and disadvantages of each method are analyzed and compared.
Keywords:Implicit function;Explicit method;Direct method;Formula method;Differential method;Logarithmic derivative method
