Question 1031176
.
Write the expression in terms of sine only.
-√3sin(x) + cos(x)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{-sqrt(3)*sin(x) + cos(x)}}} = {{{2*((-sqrt(3)/2)*sin(x) + (1/2)*cos(x))}}} =         ( substitute here {{{-sqrt(3)/2}}} = cos(150°)  and  {{{1/2}}} = sin(150°) )

= {{{2*(cos(150^o)*sin(x) + sin(150^o)*cos(x))}}} =                   ( next use the formula  {{{cos(alpha)*sin(beta) + sin(alpha)*cos(beta)}}} = {{{sin(alpha + beta)}}} )

= 2sin(150° + x).
