<H2>COSD Cosine Degrees Function
</H2>
<P>
Section: <A HREF=sec_mathfunctions.html> Mathematical Functions </A>
<H3>Usage</H3>
Computes the cosine of the argument, but takes
the argument in degrees instead of radians (as is the case
for <code>cos</code>). The syntax for its use is
<PRE>
y = cosd(x)
</PRE>
<P>
<H3>Examples</H3>
The cosine of 45 degrees should be <code>sqrt(2)/2</code>
<PRE>
--> cosd(45)
ans =
0.7071
</PRE>
<P>
and the cosine of <code>60</code> degrees should be 0.5:
<PRE>
--> cosd(60)
ans =
0.5000
</PRE>
