[LON-CAPA-admin] tex rendering problem?

[Moore, Nathan T]

Hi,

I have a few problems that use the <m>$x^2=4$</m> latex syntax for math rendering.  

Some of my students tell me that the problem code

<p>
What is <m>$\vec{A}\cdot\vec{C}$</m>?
</p>

renders on their screen as the bare ASCII text:

What is [(A)\vec].[(C)\vec]?

When I look at this problem on my laptop I see normally rendered Computer Modern tex output.  Is there a security or config setting on my students' computers that I should attend to?  

These problems live in the public repository, /res/winona/NMoore/openstax-university-physics-1/ch2-vectors/

Any suggestions appreciated!

Nathan



Problem follows
<problem>

<script type="loncapa/perl">
#Enter the computations here
$a=&random(1,10,1);
$b=&random(1,10,1);
$c=$a+$b;
$i_dot_b=5.0*&cos(53*&acos(-1.0)/180.0)
</script>
