sin&lt;sup&gt;2&lt;/sup&gt;&lt;font face = &quot;symbol&quot;&gt;q&lt;/font&gt;

means the same as

(sin&lt;font face = &quot;symbol&quot;&gt;q&lt;/font&gt;)&lt;sup&gt;2&lt;/sup&gt;

sin&lt;sup&gt;2&lt;/sup&gt;&lt;font face = &quot;symbol&quot;&gt;q&lt;/font&gt;

is less to write than

(sin&lt;font face = &quot;symbol&quot;&gt;q&lt;/font&gt;)&lt;sup&gt;2&lt;/sup&gt;

sin&lt;sup&gt;2&lt;/sup&gt;30° = (0.5)&lt;sup&gt;2&lt;/sup&gt; = 0.25

Edwin&lt;/pre&gt;
