LaTeX Help please getting the LaTeX correct for this vector expression

AI Thread Summary
To properly format the expression $\vec{b} - t\vec{a}$ with a long arrow, the solution is to use the notation $\overrightarrow{b - t\vec{a}}$. This method ensures that the vector notation is visually accurate and meets the desired formatting standards. The discussion highlights the importance of using the correct symbols for clarity in mathematical expressions, particularly in vector notation.

$t\vec{a}$ and $\vec{b}$ where t is a scalar times the vector a.

How can I make $\vec{b-ta}$ look right?

Solved
$$
\overrightarrow{b-ta}
$$

The trick was to use the overrightarrow

as in

\overrightarrow{b-ta}
 
I vould have said that \vec{b} - t \vec{a} was correct.

Yes, but I think they wanted the long arrow.

Long arrows shot from longbows travel farther and are more accurate when hitting a target. (jk)
