Converting a series expansion into a polynomial: convert convertir

### 5.27.25 Converting a series expansion into a polynomial: convert convertir

The convert command (see Section 5.23.26), with the option polynom, converts a series (see Section 5.36.2) into a polynomial. It should be used for operations like drawing the graph of the Taylor series of a function near a point.

For this purpose:

- convert takes two arguments:
  - series, a series.
  - polynom, the option.
- convert(series,polynom) returns series with the order_size function replaced by 0.

#### Examples

- Input:
  convert(taylor(sin(x)),polynom)
  Output:

  x− |
  x3
  6
  | + |
  x5
  120

- Input:
  convert(series(sin(x),x=0,6),polynom)
  Output:

  x− |
  x3
  6
  | + |
  x5
  120
