Question 425456
Solution:  2sin3x=1 => sin3x=1/2 => 3x=30(degree) =>x=10(degree)

Since the sinx is periodic function with period {{{2(pi)}}} we have:

  {{{x=2(pi)n+10}}} for  0< x <90 

  The solution in radian will be:

    {{{sin(3x)=1/2}}}
   
    {{{ 3x=(pi)/6}}} 

    {{{ x=(pi)/18}}} and the solution will be:

    {{{x=2*(pi)*n+(pi)/18}}}

    {{{ 0 < x < (pi)/2}}}
