Question 1094229
.
how do i solve 2sin(x) + sqr3 = 0 for 0 < x < 2pi
~~~~~~~~~~~~~~~~


<pre>
2sin(x) + sqrt(3) = 0  ====>

2*sin(x) = {{{-sqrt(3)}}}  ====>

sin(x) = {{{-sqrt(3)/2}}}  ====>

x = {{{4pi/3}}}   or/and  x = {{{5pi/3}}}.


<U>Answer</U>.  There are TWO solutions:  {{{4pi/3}}}  and  {{{5pi/3}}}.
</pre>
