### Am I plotting this function incorrectly?

Hi everyone,

Glad to getting started using Sage aspart of my uni course.

I have this function that I am plotting, but I am getting a wierd output with a specific range.

This gives reasonable ~~output:
~~output:

```
p = (x^3-7*x+2)/(cos(x)-1)
plot(p, (-5,
```~~-0.1))~~-0.1))

But changing the range looks ~~weird:
~~weird:

```
p = (x^3-7*x+2)/(cos(x)-1)
plot(p, (-5,
```~~0))~~0))

I am doing this on SageCell. Is it Sage having issues plotting the above or me setting range/scale incorrectly?

Thanks a lot,

Per
