  1. sin invisible function application theta greater or equal than fraction numerator 13 over denominator 11 end fraction    
  2. sin invisible function application theta greater or equal than fraction numerator 11 over denominator 13 end fraction    
  3. sin invisible function application theta greater or equal than fraction numerator square root of 3 over denominator 2 end fraction    
  4. sin invisible function application theta greater or equal than fraction numerator 1 over denominator square root of 2 end fraction    

The correct answer is: sin invisible function application theta greater or equal than fraction numerator 11 over denominator 13 end fraction
