SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python. It depends onmpmath, and other external lib...
符号微分(Symbolic Differentiation)属符号计算的范畴,其计算结果是导函数的表达式。符号计算用于求解数学中的公式解(也称解析解)。和前文数值解不同的是,通过符号位分得到的是解的表达式而非具体的数值。根据基本函数的求导公式以及四则运算、复合函数的求导法则,符号微分算法可以得到任意可微函数的导数表达式。
The only truly reliable way to do so would require using symbolic computation on conventional symbols like π.Similarly, you can’t create a fraction whose denominator is zero because that would lead to a division by zero, which is undefined and has no meaning in mathematics:...
