sin(t)<(1)32\sin{\left(t \right)} < \frac{\left(-1\right) \sqrt{3}}{2}
sin(t) < -sqrt(3)/2
Detail solution
Given the inequality:
sin(t)<(1)32\sin{\left(t \right)} < \frac{\left(-1\right) \sqrt{3}}{2}
To solve this inequality, we must first solve the corresponding equation:
sin(t)=(1)32\sin{\left(t \right)} = \frac{\left(-1\right) \sqrt{3}}{2}

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
x0<x47x_{0} < x_{47}
For example, let's take the point
x0=x47110x_{0} = x_{47} - \frac{1}{10}
=
11851.1346868919110-11851.1346868919 - \frac{1}{10}
=
11851.2346868919-11851.2346868919
substitute to the expression
sin(t)<(1)32\sin{\left(t \right)} < \frac{\left(-1\right) \sqrt{3}}{2}
sin(t)<(1)32\sin{\left(t \right)} < \frac{\left(-1\right) \sqrt{3}}{2}
            ___ 
         -\/ 3  
sin(t) < -------
            2   
         

Then
x<11851.1346868919x < -11851.1346868919
no execute
one of the solutions of our inequality is:
