Question 1043627
.
It is given that sin (tetha)=k, where tetha is an angle measured in radians and 3pi/2 < tetha < pi. 
If sin Beta = k, which of the following could be the value of Beta?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
1.  If {{{sin(theta)}}} = {{{sin(beta)}}} then {{{theta}}}- {{{beta}}} = {{{2k*pi}}}, where "k" is integer.

    Is this tip enough for you?


2.  Your inequality  {{{3pi/2}}} < {{{theta}}} < pi  from the condition is something impossible.
