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]]
