Question 1205810
.
Rewrite each expression as a function of a single angle. 
You do not need to solve for the function at that angle.
{{{2*sin(63^o)*cos(63^o)}}}
~~~~~~~~~~~~~~~~~~~~~



<pre>
Use the formula of double argument for sine function

    sin(2a) = 2*sin(a)*cos(a)


and get

  {{{2*sin(63^o)*cos(63^o)}}} = sin(2*63°) = sin(126°).    <U>ANSWER</U>


The last expression is what you want to get.
</pre>

Solved.
