Converting a series expansion into a polynomial

### 11.1.25 Converting a series expansion into a polynomial

The convert command (see Section 10.1.10), with the option polynom, converts a series (see Section 13.5.2) into a polynomial. It should be used for operations like drawing the graph of the Taylor series of a function near a point.

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

#### Examples

convert(taylor(sin(x)),polynom)

x− |
x3
6
| + |
x5
120

convert(series(sin(x),x=0,6),polynom)

x− |
x3
6
| + |
x5
