How do I included mathematical symbols into my body text. In this example I want to include the Greek lowercase letter alpha (α):
The ball is deflected by an angle \alpha away from the line of approach of the cue
When I compile the above I get the following error:
! Missing $ inserted.
<inserted text>
$
l.101 ...e cue
Mathematical symbols must be declared in a mathematical environment. In the body text this can be invoked by surrounding the symbol in dollar symbols, i.e.:
The ball is deflected by an angle $\alpha$ away from the line of approach of the cue
