Hi I want to to show graphically:
$$\vec{x} = \vec{p} + t(\vec{q}-\vec{p})$$ for vectors $\vec{x},\vec{p},\vec{q}$ and t varying from 0 to 1 in $\mathbb{R}^2$. So basically the vector $\vec{x}$ goes along line segment between P and Q. Obviously I could define specific vectors $\vec{p}$ and $\vec{q}$. How could I do this?
BTW how do I type latex in this forum?
