A have a little problem using math functions with AS.  
Some of them work, some don’t, and i can’t understand why.

Here’s an example:

y=x+2 – this.\_y = this.\_x +2 – this one works  
y=x^2+2x+15 – this.\_y= this.\_x^2 + this\_x\*2 + 15 – dosen’t works

It is strange, does anyone have an idea how to use this kind of functions with the help of AS?
