# poly-derivative
基于[poly-derivative](https://www.npmjs.com/package/poly-derivative)原库1.0.0版本进行适配

> Computes the derivative a polynomial.  Formally the same thing as multiplying by the index and shifting left.

## Install
```sh
ohpm install poly-derivative
```

## Example
Compute the derivative of the polynomial `1 + 2*x + 3*x^2 + 4*x^3`:
```typescript
import polyDerivative from 'poly-derivative';

console.log(polyDerivative([1, 2, 3, 4]));
```

### Output
```
[ 2, 6, 12 ]
```

## API
#### `polyDerivative(poly: number[], result?: number[]): number[]`
Computes the derivative of a polynomial, with coefficients represented in increasing order.

* `poly` are the coefficients of the polynomial

**Returns** The derivative of the polynomial
