Discussion Overview

The discussion revolves around formatting a vector expression in LaTeX, specifically how to correctly represent the expression $\vec{b} - t\vec{a}$ with an appropriate arrow notation.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant presents the expression $t\vec{a}$ and $\vec{b}$ and asks how to format $\vec{b-ta}$ correctly.
  • Another participant suggests using the command \overrightarrow to achieve the desired formatting.
  • A different participant proposes that the expression $\vec{b} - t \vec{a}$ is also a correct representation.
  • One participant humorously comments on the preference for long arrows, suggesting they are more effective in a metaphorical sense.

Areas of Agreement / Disagreement

Participants express differing opinions on the correct formatting, with some supporting the use of \overrightarrow and others suggesting an alternative representation. The discussion does not reach a consensus on the preferred method.

$t\vec{a}$ 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)
