I aim to write a multidimensional Taylor approximation using sympy, which. returns the result without the Big-O-remainder term, as e.g. in sin (x)=x - x**3/6 + O (x**4). Naively, one could just combine the series command twice for each variable, which unfortunately does not work, as this example … Webdimensional space level. Symbolic representation is one of the promising tech-niques, since symbolic representation methods try to benefit from the wealth of search algorithms used in bioinformatics and text mining communities. The symbolic aggregate approximation (SAX) is one of the most competitive meth-ods in the literature.
