# Find minimum value of polynomial

I have a univariate polynomial with integer coefficients over [0,1] and I would like to find a minimum value. Is there an easy way to do that in sage?

Try the following:

```
f(x)=(x-3)*(x+2)^2
f.find_minimum_on_interval(0,1)
```

You have to remember that: f.find_minimum_on_interval(0,1) does NOT include the end points. This call on f(x) = (x-3)*(x+2)^2 will produce these results: (-17.99999991390072, 0.99999997130024143) While over the interval [0,1] the minimum is located at x=1 If you want to include the endpoints you would need to write something like this: min(f(0), f.find_minimum_on_interval(0,1)[0], f(1))
