oh ok i see it now. sorry, thank you very much though, that helped me out. do you by anychance know how to set restrictions on lines so that it only graphs a segment?
that's exactly what i'm trying to figure out. i'm trying to find the way to set up a domain and range on it and i still can't lol. i'll make sure to tell you if i find something. this is for a project due thursday =p
In parametric form, you may let $\displaystyle \cos(t)=\frac{x-5}{3}$ and $\displaystyle \sin(t)=\frac{y}{3}$ to get $\displaystyle \alpha(t)=(x(t),y(t))=(3\cos(t)+5,\sin(t))$ for $\displaystyle t\in[0,\pi]$.
