What is the result of the following expression: PolinomioTaylor[x^3 sin(y), y, 3, 2]?

PolinomioTaylor[x^3 sin(y), y, 3, 2] returns the power series of x^3 sin(y) with respect to y, around y = 3, up to order 2.
27sen(y) + 27sen(y) (x - 3) + 9 sen(y) (x - 3)2
sen(3) x³ + cos(3) x³ (y - 3) - (sen(3) x³) / 2 (y - 3)²
ñ^2 + 2 ñ (x - ñ)
