Taylorinfo

Function: taylorinfo (<expr>) Returns information about the Taylor series <expr>. The return value is a list of lists. Each list comprises the name of a variable, the point of expansion, and the degree of the expansion.

taylor ((1 - y^2)/(1 - x), x, 0, 3, [y, a, inf]);
 taylorinfo(%);

taylorinfo returns false if <expr> is not a Taylor series.

Example:

          (%i1) taylor ((1 - y^2)/(1 - x), x, 0, 3, [y, a, inf]);
                            2                       2
          (%o1)/T/ - (y - a)  - 2 a (y - a) + (1 - a )

2 2 + (1 - a - 2 a (y - a) - (y - a) ) x

2 2 2 + (1 - a - 2 a (y - a) - (y - a) ) x

2 2 3 + (1 - a - 2 a (y - a) - (y - a) ) x + . . .

          (%i2) taylorinfo(%);
          (%o2)               [[y, a, inf], [x, 0, 3]]

(%o1)                                true
(%i2)
